Which of the following equation will be affected by change in volume?
2) N2 (g) +O2(g) <----->2NO2(g)
3)H2(g) + Cl2(g) <----> 2HCl(g)
4) All
5) None
Answer:
None. The amount of chemicals you have, if they're equal amounts, won't change. You'll get the same mixture if you add 1 cup of OJ to 1 cup of water, compared to 100 gallons of OJ to 100 gallons of water.

If volume changes while temperature remains constant, the equation will be affected if there are unequal moles of gas on each side. Volume change = pressure change.
If the volume increases the pressure will decrease, favoring the side with more moles. If the volume decreases the pressure will increase, favoring the side with fewer moles.
2) You originally have 2 N's and 2 O's. After the reaction, you have 2 N's and 4 O's - a change in volume.
Combine this with what the person before me commented and you have the correct answer and reasoning.
Yes, it is 1. And yes, 2) is not balanced properly.
Are you referring by volume to amount of reactants?.
Being gases, all could be affected by pressure change.
2. needs to be balanced properly.
Gases will expand to fill any volume that they are put in.
1) 2SO2 + O2 <------> 2SO3
because the moles are not equal in this equation at both sides hence change in volume will affect this Increasing the volume will favour backward reaction and vice versa
only first eq get effected bocoz the no of moles are different on the both sides of the reaction. on increasing the volume the eq will shift on the left side.
