The rate law for a reaction between the substances and is given by rate =
On doubling the concentration of and halving the concentration of , the ratio of the new rate to the earlier rate of the reaction will be as
For the reaction system:
volume is suddenly reduced to half its value by increasing the pressure on it. If the reaction is of first order with respect to and second order with respect to , the rate of reaction will
diminish to one-fourth of its initial value
diminish to one-eighth of its initial value
increase to eight times of its initial value
increase to four times of its initial value
