PLS HELP, THERE CAN BE MORE THAN 1 ANSWER IN THIS QUESTION
If the activation energy of a reaction is very low, . (Check all that apply.)

1. a relatively high number of collisions between reacting particles are effective.

2. a decrease in temperature will slow the reaction.

3. the reaction occurs readily at room temperature.

The correct answer is

option 1. a relatively high number of collisions between reacting particles are effective.

Explanation:

Activation energy refers to the amount of energy which is required by the reacting substances to take part in chemical reaction. If the activation energy is higher, the molecules moves very fast and reaction does not occur. Chemical reaction occurs when the reactant possess low amount of energy.
