3. There are two decomposition reactions yielding the products below. AB+CDE+F(1saorderrxnat325C)(2ndorderrxnat325C) Which reaction takes longer to decompose 90% of the initial reactant concentration if each starts with 1.0M of its reactant at 325C ? Show by calculating the reaction time for each. Assume that rate constants of both reactions are numerically equal at given temperature. (15 p.)
