Ulemist CHM 4L. Report on Exp. 6 Page 225 Last Name: Post Lab Problem 2 (10 points). Initial concentrations and rates for the balanced reaction: raten (Al M 18). M a +bB products exp.#1: 16 2.0 | 20 exp #2 are collected in three experiments in the Table on the right What are: (a) the orders in A and B hl the overall order of the reaction, and (c) the rate constant? Enter your detailed solution below and answers in the boxes provided using correct units and sig. figs.: Solution: 1.0 2.0 exp #3: 0.50 Answers: order of kinetics in A= overall order of kinetics = order of kinetics in B

Answer 1
