Why might increasing the temperature alter the rate of a chemical reaction?
A)The molecules will have a higher kinetic energy and bump into one another harder.
B)The molecules are less reactive at higher temperatures.
C)The molecules will more likely combine with other atoms at high temperature to save space.
D)The density decreases as a function of temperature and this leads to an increase in volume which drops the rate of reaction.
E)none of the above

Question

Quizplus · Accepted Answer

Increasing the temperature increases the kinetic energy of molecules, which leads to increased collision energy, frequency, and activation energy. This results in a higher rate of reaction.
