Question 1
1.
2NO(g)⟷ N
2
(g) + O
2
(g) + heat
Is this reaction endo or exothermic?
exothermic
endothermic
Question 2
2.
2NH
3
(g) ⟷ 3H
2
(g)+N
2
(g)
If heat is a reactant in the reaction above, then the reaction is:
endothermic
exothermic
Question 3
3.
N
2
+ 3 H
2
<-> 2 NH
3
What impact did adding N
2
at t
1
have on NH
3
?
Adding N
2
shifted the reaction towards the reactants increasing NH
3
Adding N
2
shifted the reaction towards the products decreasing NH
3
Adding N
2
shifted the reaction towards the products increasing NH
3
Adding N
2
shifted the reaction towards the reactants decreasing NH
3
Question 4
4.
N
2
+ 3 H
2
<-> 2 NH
3
If heat was added at t
3
, which statement is true:
The reaction is endothermic because an increase in temperature caused the reaction to shift towards the reactants.
The reaction is exothermic because an increase in temperature caused the reaction to shift towards the reactants.
The reaction is exothermic because an increase in temperature caused the reaction to shift towards the products.
The reaction is endothermic because an increase in temperature caused the reaction to shift towards the products.
