MHT CET Chemistry question
Consider the reaction, Products. When concentration of B alone was doubled, the half-life did not change. When the concentration of A alone was doubled, the rate increased by two times. This unit of rate constant for this reaction is [AIEEE 2007]
Answer: (D)
Solution
Doubling A doubles the rate, so the order in A is 1; the half-life does not change when B is doubled, so the rate does not depend on [B] (order in B is 0, otherwise the half-life would change);
