Which of the following statements is true for a catalyzed reaction that proceeds in the forward direction?
a)The amount of product formed will be greater than for the same reaction run without a catalyst.
b)The reactants are converted to products, any intermediates that form are subsequently consumed, and the catalyst is consumed by the reaction.
c)The reactants are converted to products, any intermediates that form are subsequently consumed, and the catalyst is not consumed by the reaction.
d)None of these statements is true.
Homework Answers
Correct option is C
Explanation:
Catalyst : Which is there to change the rate of reaction without itself undergoing any change. i.e. it is there after the completion of reaction.
Thus, option b is wrong
From the Law of conservation of mass, Mass of reactants = Mass of products
As mass can neither be created nor destroyed.
Intermediates are produced during the reaction and are consumed within the reaction to give products
Thus option A is not true.

an enzyme-catalyzed reaction was carried out with the substrate concentration initially a thousand times greater than the Km for that substrate. After 9 minutes, 1% of the substrate had been converted to product, and the amount of product formed in the reaction mixture was 12micromols. If in a separate experiment, one third as much enzyme and twice as much substrate had been combined how long would it take for the same amount of product to form?

Which of the following statements is/are CORRECT? For a chemical system at equilibrium, the forward and reverse rates of reaction are equal. For a chemical system at equilibrium, the concentrations of products divided by the concentrations of reactants equals one. For a chemical system, if the reaction quotient (Q) is less than K, reactant must be converted to products to reach equilibrium.
