Question

The thermal decomposition of HCO2H is a first order
reaction with a rate constant of 2 4 x 10-3
s-1 at a certain temperature Calculate how long will it
take for three-fourths of initial quantity of HCO2H to
decompose

born2befree1995... · Answer

let the rate constant be k = 2 4 x 10-3 s-1
half life of first order reaction is T1/2 = 0
693/k
time taken for three fourths of reaction to take place is two
half lives that is 2x T1/2
hence ANS : 2 x 0 693 x 103 / 2 4 seconds
= 577 5 seconds
