Explanation / Answer

A)The units of k for a zero order reaction is mol/ L*1/ sec=M.(1/s)

part-B)zero order is rate independent

c)

For a first order reaction,

ln[A/A0]=-kt

Here, A is the concentration at ant time t, and the A0 is the concentration at time t=0, initially.

k is the rate constant, t is the time

ln[A]=kt+ln[A0]=9*10^-2=-15k+ln[A0]------------->1

ln[A]=kt+ln[A0]=4.3*10^-3=-75k+ln[A0]--------->2

0.0857=60k

k=0.0014 sec

--------------------------------

part-D)

1/[A] =kt+1/[A0]

1/0.28 M =270 k +1/[A0]-----------------1

1/0.06 M =710 k +1/[A0]-------------2

Solve both the equations

-13.09=-440 k

k=0.02975 L/mol sec =M-1 s-1
