during the course of a reaction if q < k, which of the following would be true?

When q = k the reaction is at equilibrium?

Which of the following description about enzymes is NOT true? Enzymes are not altered irreversibly during the course of reaction. Enzymes are as efficient as inorganic catalysts. Enzymes are required in small amounts. Enzymes do not change the reaction thermodynamics. Many enzymes are conjugated with nonprotein components.

Which reaction is favoured when Q = K?

If the reaction quotient Q is equal to the related equilibrium constant, K, _____. A) the reaction is at equilibrium. B) the reaction will continue to make more products. C) the reaction will consume products and make reactants. D) the reaction will release heat to achieve equilibrium. E) the value of K will increase until it is equal to Q.

When q = k the reaction proceeds in the forward direction?

Which of the following statements is TRUE? a. If Q > K, it means the forward reaction will proceed to form more products. b. If Q = K, it means the reaction is at equilibrium. c. If Q < K, it means the reverse reaction will proceed to form more reactants. d. All …

What is Q in chemistry?

Which of the following statements are true about the reaction quotient, Q? Select all that apply. a) Q expresses a particular ratio of products and reactants at any time during a reaction. b) the expression for Q is the same as the expression for K c) Q=K only at equilibrium d) the value of Q is calculate using only initial concentrations ...

Which of the following is true if Q k?

The answer is (a) If Q=K , it means that the reaction is at equilibrium. The given statement that is true is from choice (A). When the reaction quotient (Q) has an equal value with the equilibrium constant (K), there will be no shift in the chemical reaction because we consider the chemical reaction at equilibrium.

What happens if Q k?

If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.

What is Q and K in equilibrium?

and. It is important to understand the distinction between Q and K. Q is a quantity that changes as a reaction system approaches equilibrium. K is the numerical value of Q at the "end" of the reaction, when equilibrium is reached.

What happens to Q over the course of a reaction?

The reaction quotient can be used to determine in which direction a reaction will proceed. If Q = Keq, the reaction is at equilibrium. If Q < Keq, the reaction will move toward the products to reach equilibrium. If Q > Keq, the reaction will move toward the reactants in order to reach equilibrium.

Will a precipitate form if Q k?

Remember: If Q > K sp a precipitate will form (until Q decreases to K sp. If Q = K sp, equilibrium is reached - no precipitate will form. If Q < K sp, any ppt in solution will dissolve until Q increases to K sp.

How do you find the Q of a reaction?

Calculate Q for a Reaction So essentially it's the products multiplied together divided by the reactants multiplied together, each raised to a power equal to their stoichiometric constants (i.e. the numbers of each component in the reaction).Mar 30, 2020

What is K in chemistry reaction?

The rate constant, k, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction. The rate constant may be found experimentally, using the molar concentrations of the reactants and the order of reaction.Jan 2, 2021

What is the difference between the reaction quotient Q and the equilibrium constant K?

The reaction quotient is given by the same equation as the equilibrium constant (concentration of products divided by concentration of reactants), but its value will fluctuate as the system reacts, whereas the equilibrium constant is based on equilibrium concentrations.

What is K in chemistry kinetics?

The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally.Feb 21, 2022

How do you find k and q?

1:193:00K (Equilibrium Constant) vs Q (Reaction Quotient) - YouTubeYouTubeStart of suggested clipEnd of suggested clipAnd then I calculated Q. So in this first example with these initial reaction concentrations DQ wasMoreAnd then I calculated Q. So in this first example with these initial reaction concentrations DQ was thirteen point six one that's a lot less than RK. Right so in this case Q is less than K C.

Does Q change with temperature?

As long as the pressures are fixed, the temperature does not affect the instantaneous value of the reaction quotient.May 8, 2016

What is the correct expression for the equilibrium constant K?

Write the equilibrium constant expression for each reaction. Answer: K=[N2][O2]1/2[N2O]Feb 2, 2022
