Question

Suppose you wanted to calculate the heat of reaction for the formation of ammonia gas and gaseous hydrochloric acid from solid ammonium chloride.
a. Write a balanced equation for this reaction.

Answer 1

the equation for the reaction describe in the question is NH4Cl (s) --> NH3 (g) + HCl (g)

the equation of heat reaction :
ΔH25° = (ΔH25° NH3 + ΔH25° HCl) - (ΔH25° NH4Cl)

use the table from basic chemical engineering calculations of himmelblau or felder to find ΔH25°.ΔH25° of products minus ΔH25° of reactants.

hope this help

Answer 2

Answer:

Above is correct, but the heat of reaction is 176.18 J/mol
