The table shows the conditions during two trials of a reaction. Reaction Conditions
Trial Temperature Catalyst
1 60 °C used
2 45 °C not used

Assuming that other conditions remain the same during the two trials, which of the following is true for the reaction?
1) The reaction pathway for the two trials is different.
2) The activation energy barrier is lower during Trial 2 than Trial 1.
3) The same number of reactant particles reached the transition state in Trial 2
as in Trial 1.
4) The number of particles having the required activation energy is higher for
Trial 2 than Trial 1.
