Answer:

<em>What quantity dictates the speed of a reaction?</em> The activation energy

Explanation:

According to the collision theory, when molecules collide, they must overcome an energy barrier for the reaction to take place. This energy, known as activation energy, is represented by the difference in energy between the initial state and the transition state. The higher the activation energy, the slower the reaction. That's why catalysts reduce the activation energy to accelerate the reaction.

Use enthalpies of formation to determine the ΔHreaction for the reaction
Daniel [21]

Answer:

The enthalpy is increased by the increased heat of the reaction.

Explanation:

In this reaction, as the transition from solid to liquid state, enthalpy increases, that is, the heat applied to change its state is greater and this increases, reaching a mayor disorder.

If the reaction increases its heat, and a liquid state passes, the enthalpy increases, therefore the disorder also and the entropy will also be increased.

Use the kinetic energy equation to explain why speed has a greater impact on kinetic energy than mass.​
Lerok [7]

Answer: <em>Hopefully this helps! sorry if not. :))</em>

<em></em>

<em>Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.</em>
