Homework Help: chemistry

Posted by Kristy on Wednesday, May 23, 2007 at 2:13am.

Predict the effect of each of the following on the indicated equilibrium system in terms of which reaction will be favored (forward, reverse, or neither)

H2(g)+Cl2(g)<=>2HCl(g) +184 kJ

A)addition of Cl2
B)removal of HCl
C)increased pressure
D)decreased temperature
E)removal of H2
F)decreased pressure
G)addition of a catalyst
H)increased temperature
I)decreased system volume

I really don't get these at all. Please help! Thanks so much!


The forward reaction gives off heat. Would the abilty to give off heat be enhanced if it were cooled?

The forward reaction produces as many volumes of gas as it had in the beginning. Will that reaction be favored if pressure is changed?

If the reactants are removed, would not the reverse reaction tend to increase them?

I will be happy to critique your thinking.
