Rate expression problems UNIS 2020
Determine the rate of reaction for the following reaction using the data provided. Calculate the rate constant and determine its units. Q1: Answer on the next page
q2: Determine the rate expression and the value and units of k for: Answer
The effect of concentration on rate • Case 1: zero order reaction: The rate is not affected by the concentration of reactant; double the concentration and rate stays the same. Rate = k[R]0 = k
Case 2: First order with respect to the reactant. The rate is directly proportional to the concentration of the reactant. Double the concentration the rate doubles. Rate = k[R]1
Case 3: second order reaction; double the concentration and the rate quadruples (multiplied by 4). Rate = k[R]2
