Pitanje 3

3.

N₂ + 3 H₂ <-> 2 NH₃
What impact did adding N₂at t₁have on NH₃?

Adding N₂ shifted the reaction towards the reactants increasing NH₃

Adding N₂ shifted the reaction towards the products decreasing NH₃

Adding N₂ shifted the reaction towards the products increasing NH₃

Adding N₂ shifted the reaction towards the reactants decreasing NH₃

4.

N₂ + 3 H₂ <-> 2 NH₃
If heat was added at t₃, 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.
