Question

Which of the following change always leads to an increase in the rate constant for a reaction? (i) Decreasing the temperature (ii) Decreasing the activation energy (iii) making the value of DeltaE more negative

Answer 1

A temperature change occurs when temperature is increased or decreased by the flow of heat. This shifts chemical equilibria toward the products or reactants, which can be determined by studying the reaction and deciding whether it is endothermic or exothermic
