Question

For the reaction
N2O4(g) ---> 2NO2(g) ,which of the following disturbances will cause an increase in NO2(g) concentration?

1. a decrease in temperature
2. removal of some N2O4(g)
3. need
H for the reaction to predict
4. an increase in temperature
5. an increase in pressure

Answer 1

#2 and #5 will cause a decrease in NO2. All of the others are about T; I would like to see dH for the reaction.

Answer 2

An increase in temperature because the reaction is endothermic.
