6.25*10^-3
a)
consider experiment 1 and 2
Here only the concentraion of A doubles and rate doubles. SO order
with respect to A is 1
consider experiment 2 and 3
Here only the concentraion of b doubles and rate becomes 4 times.
SO order with respect to B is 2
consider experiment 1 and 4
Here only the concentraion of C doubles and rate remains same. SO
order with respect to C is 0
b)
rate law is:
rate = k [A] [B]^2
c)
rate = k [A] [B]^2
consider experiment 1.
rate = 6.25*10^-3 M/s, [A]= 0.05 M, [B]= 0.05 M
rate = k [A] [B]^2
6.25*10^-3 = k * (0.05)*(0.05)^2
k= 50 M^-2 S-1
