The decomposition reactions of two different environmental pollutants are monitored over time. Noted are the time points where the pollutants reach 50%, 25%, and 12.5% of the initial environmental concentration.For pollutant A, which of the following is true? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a The decomposition of pollutant A is a zeroth order reaction. b The decomposition of pollutant A is a first order reaction. c The decomposition of pollutant A is a second order reaction. d More information is needed to determine the order of the decomposition reaction of pollutant A.
