Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that …
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energ…

Chapter 10, Problem 10.95QP

You are given the following data.

H 2 ( g )   →   2 H ( g )   Δ H ° =   436.4   k J / m o l B r 2 ( g )   →   2 B r ( g )   Δ H ° =   192.5   k J / m o l H 2 ( g )  +  B r 2 ( g ) →   2 B r ( g )   Δ H ° =   − 72.4   k J / m o l

Calculate ΔH° for the reaction

H 2 ( g )  +  B r ( g ) →   H B r ( g )
