Question

In first order reaction 60%
of the reactant decomposes in
45min, calculate half-life for
the reaction
a) 0.0204 min
b) 34 min
c) 0.3979 min
d) 0.34 min​

Answer 1

Answer:

34 mins

Explanation:

let us assume a = 100 ... they mentioned that 60% was decomposed so a-x = 100-60 = 40 then by using the formula we can find value of K. By using the half life period we can find the t1/2
