Answer 1

Answer #1

The speed of the experiment is calculated:

Rate = - Δ [B] / Δt = - (2.35x10 ^ -5 - 1x10 ^ -3) / 200 = 4.88x10 ^ -6

a) The value of k is determined:

K = Rate / [A] * [B] * [C] ^ 3 = 4.88x10 ^ -6 / (2 * 2 * 1x10 ^ -3) = 0.00122

b) The average speed is calculated, taking as pseudo order one with respect to B, because A and C are as excess:

t 1/2 = ln2 / k = ln2 / 0.00122 = 568.15 s

If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
