A sample of N2O3 (g) has a pressure of 0.017 atm. The temperature of (in K) is then doubled and the N2O3 undergoes complete decomposition to NO2 (g) and NO (g). Find the total pressure of the mixture of gases assuming constant volume and no additional temperature change.
The proposed mechanism for a reaction is 1. ClO-(aq) + H2O(l) => HClO(aq) + OH-(aq) SLOW 2. I-(aq) + HClO(aq) => HIO(aq) + Cl-(aq) FAST 3. OH-(aq) + HIO(aq) => H2O(l) + IO-(aq) FAST Which of the following would be a rate law for the reaction
