JEE Main 2024 Chemistry question
Consider the following reaction A + B → C. The time taken for A to become 1/4th of its initial concentration is twice the time taken to become 1/2 of the same. Also, when the change of concentration of B is plotted against time, the resulting graph gives a straight line with a negative slope and a positive intercept on the concentration axis. The overall order of the reaction is .
Answer: 1
Solution
t₁/₄ = 2t₁/₂ means first order in A. A linear fall of [B] with time means zero order in B, so the overall order is 1.
