Expert Solution
Step 1

For first order reaction , the integrated rate law equation is 

k = 2.303tlog[R]o[R]

k = rate constant

t = time 

[R]o = initial concentration of reactants

[R] = final concentration of reactants that left un reacted

 

Half life (t1/2) of first order reaction is given by 

t1/2 = 0.693/k
