State what effect each of the following procedures will have on the rate of this

reaction, and explain in terms of the collision theory why the procedure has the stated

effect.

b) More O2(g) is added in the same volume

a) rate  – the lower temperature means less kinetic energy means fewer

effective collisions

b) rate – higher pressure means greater concentration of reactants

means increased chance of collisions and  more effective collisions

c) no change – SO2(g) is a product. Only changes in reactant

concentrations will effect the rate of a forward reaction.

d) rate – grinding up the sulfur increases it’s surface area, increasing

the chance of collisions

e) rate  – increasing the volume lowers the pressure which effectively

lowers the concentration O2(g) (a reactant) meaning decreased chance of

collisions and  fewer effective collisions
