Question

Given the following exothermic reaction:
COCl2 (g) <-> CO(g) + Cl2 (g)
Provide 3 different ways to reduce the concentration of CO using LeChateliers principle. Briefly
explain each method.
a)
b)
c)

Answer 1

increase pressure, increase concentration, increase temp/

Answer 2

doesnt help much

Answer 3

Sure it does.

Answer 4

for a) i put

Increase (Cl2)

Answer 5

idk what to write for b and c

Answer 6

Increasing the concentration would push the reaction backward and decrease the concentration of CO, so (a) looks good.

Answer 7

Since you are told the reaction is exothermic, increasing the temp would also push the reaction backward.

Answer 8

And, because the right side of the reaction has more molecules, increasing the pressure would also push the reaction backward.
