1. Write the rate expressions for the following reactions in terms of the disappearance of the reactants and appearance of products: a) CH4(g) + 2O2(g) → CO2(g) +2H2O(g) b) 4NO2(g) + O2(g) → 2N2Os(g) (4 mks) 2. N2(g) + 3H2(g) → 2NH3(g) Suppose that at a particular moment during the reaction molecular hydrogen is reacting at a rate of 0.074 M/s. a) what rate is ammonia being formed? b) At what rate is molecular nitrogen reacting? (4 mks) 3. Consider the reaction: S208?- (aq)+ 31 (aq) → 250.?- (aq) + 13 (aq) from the following data, obtained at a certain temperature, a) determine the rate law b) calculate the rate constant c) determine the initial rate of reaction when the concentration of S2O8? is 0.12M and that of l' is 0.06M. (8 mks) Initial rate of (M/S) 2.2x104 1.1x104 2.2x10-4 (SzO82-1 (M) 0.08 0.08 0.16 [1] (M) 0.034 0.017 0.017 4. Consider the reaction: AB The rate of the reaction is 1.6 x 102 M/s when the concentration of Ais 0.35M. Calculate the rate constant if the reaction is a) first order in A and b) second order in A. (4 mks)
