A reaction profile gives the following energy values.
| Stage | Energy (kJ/mol) |
|---|---|
| Reactants | 120 |
| Peak | 185 |
Two collisions between reacting particles have energies of 52 kJ/mol and 71 kJ/mol.
Calculate the activation energy for the reaction. Use your answer to predict which of the two collisions could lead to a reaction. Explain your prediction.
