Which condition results in an activation energy that allows the reaction to occur more easily?

reducing the concentrations of reactant molecules

decreasing the temperature

decreasing the surface area of the particles

adding a catalyst

I think adding a catalyst

Explanation:

From what I found, any of the first 4 don't work, reducing the concentrations of reactant molecules just decreases the chances of it reacting, decreasing the temperature does more or less the same, as it takes away energy, decreasing the surface area of the particles does more or less nothing in this situation, but for a reaction to occur, you need to add energy, which only the catalyst does. good luck!

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
