Reactant a can participate in both of these reactions: 1) a + b c + d grxn = –15.6 kj 2) a + e f + g grxn = –20.5 kj reaction 1 has a much higher rate than reaction 2 under the same reaction conditions. explain this observation in terms of activation energy.

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
