As you provided the rate law expression in Part A (it is showing correct)
Rate = k [A]2[B]2
Using the table let us calculate k first,
1.1 * 10-2 = k(0.30)2(0.100)2
k = 1.2 * 10
Given that, [A] = 0.5 M and [B] = 0.075 M
So, the initial rate of formation of C,
Rate = 1.2 * 10 (0.50)2(0.075)2
Rate = 0.017 M/s
