![4. Consider the reaction: 2 A + B → products
The tentative rate law is: rate = k [A]* [B]
2 experiments were performed.
For Exp. 2: [A]o = 1.000 x 10° M; [B]o = 0.50 M The conc of A was tracked.
This is an isolation experiment which simplifies the determination of the rate law.
Use integrated rate equations to determine
The order wrt [A].
For Exp. 1: [A]o = 1.000 x 10³ M; [B]o = 1.00 M
