did I do this right

Question

Consider the following reaction at equilibrium
N2(g) + O2(g) + heat < = > 2NO(g)
Indicate how each of the following will shift the equilibrium

a. raising the temperature of the reaction.
b. decreasing the volume of the reaction container.
c. adding a catalyst
d. adding N2

my answer
a. shifts toward products
b. shifts toward reactants
c. change occurs
d. shifts toward reactants

Thanks

Answer 1

Two right!

a. shifts toward products
agreed, it is endothermic.
b. shifts toward reactants
No - No change in the position of the equilibrium as
2 moles -> 2 moles
c. change occurs
No - No change in the position of the equibrium it just gets there more quickly.
d. shifts toward reactants
Agreed

Answer 2

d. shifts toward reactants
No - it shifts towards the products.

Sorry typing too quickly and not reading the question!

Answer 3

sorry
i know but i cannot tell
