Why does an increase in temperature result in an increase in reaction rate?a) an increase in temperature raises the activation energy which increases the reaction rate. b) an increase in temperature causes the molecules to increase in size which increases reaction rate. c) an increase in temperature decreases the concentration of reactants which increases reaction rate. d) an increase in temperature causes an increases the number of collisions which increases reaction rates.

I believe your answer is A, but im not sure.

D) An Increase in temperature causes increases the number of collisions, which increases reaction rates.

Explanation:

Particles can only interact when they collide, increasing a substance's temperature will increase the movement of particles, which in turn increases the chances of collisions between these particles. Increasing the collisions between molecules increases the reaction rates.

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
