(a) Explanation For the reaction, 2 X + Z → Product The general rate law is, Rate = k [ X ] a [ Z ] b Where, k is the rate constant for the reaction. [ X ] is the concentration of X at the given time. [ Z ] is the concentration of Z at the given time. a is the order of the reaction with respect to X . b is the order of the reaction with respect to Z . When the concentration of X is 0.50 M and the concentration of Z is 0.50 M , the rate of the reaction is 3.2 × 10 2 M/s . Then, the rate law is given as, 3.2 × 10 2 M/s = k [ 0.50 M ] a [ 0.50 M ] b …… (1) When the concentration of X is 0.50 M and the concentration of Z is 0.75 M , the rate of the reaction is 7.2 × 10 2 M/s . Then, the rate law is given as, 7.2 × 10 2 M/s = k [ 0.50 M ] a [ 0.75 M ] b …… (2) Divide equation (2) by (1), 7.2 × 10 2 M/s 3.2 × 10 2 M/s = k [ 0.50 M ] a [ 0.75 M ] b k [ 0.50 M ] a [ 0 (b) Interpretation Introduction To determine: The rate constant for the given reaction. (c) Interpretation Introduction To determine: The rate of the reaction, if the initial concentration of X is 0.75 M and Z is 1.25 M .
