Question

For a chemical reaction: X -> Y, the rate of reaction increases by a factor of 1.837 when the concentration of X is increased by 1.5 times. The order of the reaction with respect to X is

Prashant Kotian · Accepted Answer

Correct answer: B. rate2 / rate1 = ([X]2 / [X]1)^n => 1.837 = (1.5)^n. Taking logarithms on both sides: log(1.837) = n * log(1.5) => n = 0.264 / 0.176 = 1.5.
