Heat flows from _______ to ______ objects

Phase changes: ice to water to steam

Phase changes: steam to water to ice

Select all the processes that are exothermic. The system is underlined in each example.

Select all the processes that are endothermic. The system is underlined in each example.

$$O_2\left(g\right)\ +\ 2\ H_2\ \left(g\right)\ \rightarrow\ 2\ H_2O\ \left(g\right)\ +\ Energy$$  

What is the Heat of Reaction $$\Delta H$$  for this reaction?

How much activation energy is needed for this reaction?

What type of reaction is this?

What kind of reaction is this: 2KI + MgCl₂ + 200KJ ----> 2KCl + MgI₂

This symbol indicates that a reaction is _____

(🡹 pressure shifts in direction of fewer gas molecules)

(🡻 pressure shifts in direction of more gas molecules )

N₂(g) + 3H₂(g) ↔ 2 NH₃(g) + heat

Increasing the pressure will cause the equilibrium to:

🡹 temperature favors endothermic reaction Shift away from heat 🡻 temperature favors exothermic reaction Shift towards heat

N₂(g) + 3H₂(g) ↔ 2 NH₃(g) + heat

Increasing the temperature will cause the equilibrium to:

(Concentration increase shift away from increase)

(Concentration decrease shift toward decrease)

N₂(g) + 3H₂(g) ↔ 2 NH₃(g) + heat

Decreasing H₂ will cause the equilibrium to:

(Concentration increase shift away from increase)

(Concentration decrease shift toward decrease)

N₂(g) + 3H₂(g) ↔ 2 NH₃(g) + heat

Removing N₂ will cause the equilibrium to:

(Concentration increase shift away from increase)

(Concentration decrease shift toward decrease)

N₂(g) + 3H₂(g) ↔ 2 NH₃(g) + heat

Increasing H₂ will cause the equilibrium to:
