Answer to Question #187346 in General Chemistry for Salvino Saji Henry

Question

The reaction 2A+B-->C+D obeys the rate equation, rate = k [A]^2 [B]^1/2. Find the order of this reaction when A is present in large excess

Answer 1

 If A is present in large excess, then the rate of the reaction will be independent of A and will depend only on the concentration of B. The overall rate of the reaction will be 1/2.
