Question

[Single-digit Integer] For a chemical reaction A + B -> Products, the order is one with respect to each A and B. The sum of x and y from the following data is: Rate (mol L^-1 s^-1): 0.10, 0.40, 0.80 [A] (mol L^-1): 0.20, x, 0.40 [B] (mol L^-1): 0.05, 0.05, Y

Prashant Kotian · Accepted Answer

Correct answer: 0001. Rate = K [A] [B]. From first data point: 0.10 = K (0.20) (0.05) => K = 10 L mol^-1 s^-1. From second data point: 0.40 = 10 x x x 0.05 => x = 0.80 M. From third data point: 0.80 = 10 x 0.40 x Y => Y = 0.20 M. Sum of x and y = 0.80 + 0.20 = 1.0 (0001).
