The following reaction is conducted: 2 A(g) + B(g) → A2B(g)
A mechanism is postulated by a chemist as follows:
2A(g) + B(g) --> A₂B(g) slow
A₂B(g) + B(g) --> A₂B(g) + B(g) fast
determine the rate law expression consistent with this mechanism.
A. rate = k[A]²[B]
B. rate = k[A][B]
C. rate = k[A₂]²
D. rate = k[A₂]²[B]
E. rate = k[A₂][B]
