Question

Consider a hypothetical reaction between A, B, and C that is first order in A, zero order in B, and second order in C.

(a) Write the rate law for the reaction.
(b) How does the rate change when [A] is doubled and the other reactant concentra- tions are held constant

Answer 1

(a) Rate = k[A][C]²

(b) If [A] is doubled, then the rate of reaction will be doubled as well.

Step-by-step explanation:

(a) The rate is equal to the multiplication of a constant and the concentrations of all reactants, each to the power of their order.

Rate = k[A]¹[B]⁰[C]² = k[A][C]²

(b) Looking at the previous equation we can see that if [A] is doubled, then the rate of reaction will be doubled as well.
