Question

question 3 as a chemical reaction happens, how does the reaction rate change? it gets faster. it gets slower. it stays the same.

Explanation:

A chemical reaction's rate is defined as the speed at which reactants are converted to products. As the reaction proceeds, reactant concentrations decrease. According to collision theory, a lower concentration of reactants means fewer effective collisions occur per unit time, so the reaction rate slows down.

Answer:

It gets slower.
