could you check this?
AB(g) → A(g) + B(g)
Rate = k[AB]^2
k = 0.2L/mol∙S
How long will it take for [AB] to reach 1/3 (one third) of its initial concentration of 1.50M? What is [AB] after 10.0 seconds?
2nd order overall reaction so:
part A
1/[A] - 1/[A]o = (k)(t)
1/0.5 - 1/1.50 = (0.2)(t)
6.667 = t
part B
1/[A] - 1/1.5 = (0.2)(10 s)
[A] = 0.375
