Can someone please check the following answers for me...THANK YOU!
1)Raising the temperature of a reacting system increases the rate of reaction but does NOT increase the: NUMBER OF COLLSIONS
2)Activation energy is: AN ENERGY BARRIER BETWEEN REACTANTS AND PRODUCTS
3)A catalyst works by: LOWERING THE ACTIVATION ENGERY BARRIER

2 and 3 are correct. 1 is correct if you are discussing the reaction rate at constant pressure, but at constant volume the collision rate does increase slowly with temperature (in proportion to sqrt T)
