Reaction is endothermic or exothermic

WebSince heat left the system, the sign of q r e a c t i o n is negative, and the reaction is exothermic. As a teacher, I have found that getting system boundaries and the signs right is one of the biggest problems students have. If you focus on getting that concept down early - and really understanding why they are that way, you are well on your way.
