Explanation / Answer
if we observe the trial 1 &trial2
the rate of the reaction increases 2 times w.r.t. increse conc. of A by 2 times
order w.r.t. A is 1
if we observe the trial 3 &trial2
the rate of the reaction increases 4 times w.r.t. increse conc. of B by 2 times
order w.r.t. B is 2
if we observe the trial 1 &trial 4
No change in the rate of the reaction. w.r.t. increse conc. of C by 2 times
order w.r.t. c is 0
b) rate = K3[A][B]^2[C]^0
K3 = 1.22*10^-1/(0.06)*(0.2)^2
K3 = 50.83 M^-2/sec
