following best explains the above?
A. high-temperature meltdown
the reactants so it is easier to
react
O
B. High temperature increases
the number of high energy
collisions
C. reactants can evaporate
when they are heated up
D. Products favor higher
temperature reactants.

High temperature increases the number of high energy collisions

Explanation:

Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly.
