Explain how the Maxwell Botlzmann distribution curve would change with an increase in temperature
-particles have more kinetic energy and move faster, many more will have energy equal/greater than Ea, shifting the curve to the right with a lower peak

What effect does an increase in concentration have on rate of reaction?
Particles closer together, more collisions mean more successful collisions and increased rate
