The increase of effective collisions will result in product particles forming faster as the energy in the particle is greater than the activation energy. Question 2 the answer is C. Remember that pressure will only affect reactants that are all in the GASEOUS state.Example will be the production of ammonia. I hope this helps =) In question 1, the answer is D.
-Higher conc leads to higher freq of effective collisions.
-It has a larger surface area when it is powered so more particles are exposed for reaction

ps. The increase of effective collisions will result in product particles forming faster as the energy in the particle is greater than the activation energy.

Question 2 the answer is C. Remember that pressure will only affect reactants that are all in the GASEOUS state.Example will be the production of ammonia.

I hope this helps =)
