Predict the rate law for the reaction 2BrO(g)-> Br2 (g) +O2 (g) if the following conditions hold true: Use k to represent the rate constant and place brackets [ ] arounds the molecular or atomic formula to designate concentration. The rate triples when [BrO] triples. Part 2 When [BrO] is halved, the rate decreases by a factor of 4. Part 3 The rate is unchanged when [BrO] is tripled.
