In a reaction A rarr products , when start is made from 8.0 xx 10^(-2) M of A, half life is found to be 120 minute. For the initial concentration 4.0 xx 10^(-2) M , the half life of the reaction becomes 240 minute. The order of the reaction is :

The rate constant of a first order reaction is 3 xx 10^(-6) per second. If the initial concentration is 0.10 M , the initial rate of reaction is

The rate of a reaction starting with initial concentration of 2 xx 10^(-3) and 1 xx 10^(-3) M are equal to 2.40 xx 10^(-40) and 0.60 xx 10^(-4) M s^(-1) , respectively. Calculate the order or reaction w.r.t. reactant and also the rate constant.
