Q7 of 26 Page 1

For a reaction , the rate is given by

Rate


(a) How is the rate of reaction affected, if the concentration of A is doubled?


(b) What is the overall order of the reaction, if B is present in large excess?


(a) Rate of the reaction increases 4 times.


if concentration of A is doubled, then




(b) The overall order of the reaction will be 2. When B is present in large excess the rate of the reaction becomes independent of the concentration of B and is solely dependent on the concentration of A. the order of the reaction with respect to A is 2 hence the order of the overall reaction will also be 2 when B is present in large excess.
