A 1.0 L flask is filled with NO and O2 initially, and after the reaction establishes equilibrium, the flask is found to contain 0.0018 mol NO, 0.0012 mol O2 and 0.78 mol NO2. What is the value of the equilibrium constant, Kc, at this temperature? 2NO(g) + O2(g) ⇌ 2NO2(g)

The decomposition of hydrogen peroxide, H2O2(aq), is proposed to follow a reaction mechanism of: Step 1: H2O2(aq) + Br–(aq) → H2O(l) + BrO–(aq) Step 2: BrO–(aq) + H2O2(aq) → H2O(l) + O2(g) + Br–(aq) What is the catalyst, and what is the effect of having a catalyst present?
