When heat (H) is absorbed from the surroundings then your H will be positive (+).
This is an endothermic reaction.

Heat Transfer During a Reaction

When HEAT (H) is released from the system to the surroundings then your H will be negative (-). This is and exothermic reaction.

Multiple Choice

When HEAT (H) is released from the system to the surroundings

then your H will be negative (-).

What type of reaction is this?

• Endothermic

• Exothermic

• Equalibrium
