MULTIPLE CHOICE QUESTION

2 mins • 5 pts

An increase in temperature typically increases the rate of reaction because ...

increase in temperature will increases both the energy of particle and frequency collisions

increase the temperature will make the number of particle decrease so that less particles will collide

increase the temperature will change the physical state of the reactant so the particle move slower

increase in temperature will provide an alternate reaction pathway to obtain products

increase in temperature will increases both the amount of particle and frequency collisions
