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.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
