You can promote collisions between molecules when you increase their kinetic energy by either increasing the temperature or pressure conditions of the systems. However, it is indicated that you must not change the energy. So, we eliminate choices C and D. Choice B is contradictory to the limitation that you do not increase the concentration of the reactants. Technically, all of the choices promote frequent collisions. But due to the limitations set, the accepted answer is letter A. When you increase the surface area by using powdered reactants instead of cubes, you increase the areas for susceptibility of collisions.

Is the process of a liquid changing into a solid when cooling a chemical reaction?
Alona [7]

Answer: The bulk of liquids separate from the standard substance through crystallization, creating a crystalline block.

Freezing is almost often an exothermic mechanism which ensures that heat is emitted when liquid transforms into concrete.

The energy emitted after freezing, known as the fusion enthalpy, is a latent heat, which is precisely the same as the energy used to melt the same volume of solid.

You’d need to lower the exponent because rounding to 3 sig figs changes the 9’s to - 1000. Keep the 0’s.
