MHT CET 2024 Chemistry question

The reaction is found to be first order in A, second order in B and zero order in C. What is the effect of increasing concentration of all reactant twice?

(A)Rate of reaction increase 8 timesCorrect
(B)Rate of reaction increases 24 times
(C)Rate of reaction increases 36 times
(D)Rate of reaction remains unaffected

Answer: (A)

Solution

The order with respect to each reactant gives the rate law (the stoichiometric coefficient 2 of A is irrelevant). When all concentrations are doubled, . The rate
