Sunil Kumar FP11 Years agothe half life of a first order reaction is 69.3 minute, the value of the rate constant k isk=.693/t1/2=.693/69.3 min-1=10^-2min-1it means that during this time period the concentration of this reaction is reduced to half.it is calcilated using the formulak=2.303/t log(N0/N)
