1. Consider the following reaction: 2 ClO2 (aq) + 2 I- (aq)  2 ClO2 - (aq) + I2 (aq) The order with respect to ClO2 was determined by starting with a large excess of I- , so that it its concentration was effectively constant. This simplifies the rate law to: rate = k’[ClO2] m where k’ = k[I- ] n . Determine the order with respect to ClO2 and the rate constant k’ by plotting the following data assuming...
