How would an increase in volume affect the following reaction?

n2 (g) + o2 (g)two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. 2no (g)

the equilibrium would shift to the right.
the equilibrium would shift to the left.
there would be no change to equilibrium.
the effect on equilibrium cannot be determined.

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
