Nitrogen oxide reacts with hydrogen at elevated tempera- tures according to the following chemical equation: 2 NO(g) + 2 H2(g) → N2(g) + 2 HzO(g) It is observed that, when the concentration of H, is cut in half, the rate of the reaction is also cut in half. When the concentration of NO is multiplied by 10, the rate of the reaction increases by a factor of 100. (a) Write the rate expression for this reaction, and give the units of the rate constant k. (b) If [NO] were multiplied by 3 and [H;] by 2, what change in the rate would be observed?
