For the chemical reaction X → Y, it is observed that, on doubling the concentration of ‘X’, the reaction rate quadruples. If the reaction rate is proportional to Cx n, then what is the value of „n‟ ?
Correct answer: B
Explanation
The rate is proportional to [X]^n. If doubling [X] (2[X]) quadruples the rate (4 times), then 2^n = 4. This means n must be 2.
