Answer 1

Answer:

Explanation:

For first order reaction we have:-

K=  

t

1

​  

ln(  

a−x

a

​  

)           −(i)

where, K= rate constant

            t= time

            a= initial concentration of the reactant

            x= amount of reactant reacted in time t

Case I: t=20 min

x=  

100

20

​  

×a⇒x=0.2a    (∵20 % reaction is complete)

⇒ a−x=0.8a
