Answer to Question #204803 in Chemistry for Jake

Question

For the reaction:

PCl3(g) + Cl2(g) ⇌ PCl5(g) H = -92.5 kJ

State:

 i) the direction of shift and ii) effect on [PC13] if the following changes are made:

i) temperature goes up

ii) chlorine is added

iii) volume drops

iv) a catalyst is added

I need help with this

Answer 1

i) temperature goes up - forward reaction velocity goes up (shift to the right), PCl3(g) concentration decreases

ii) chlorine is added - forward reaction velocity goes up (shift to the right), PCl3(g) concentration decreases

iii) volume drops - forward reaction velocity goes up (shift to the right), PCl3(g) concentration decreases

iv) a catalyst is added - forward reaction velocity goes up (shift to the right), PCl3(g) concentration decreases
