A 100. mL sample of 0.200 M aqueous hydrochloric acid is added to 100. ml of 0.200 M aqueous ammonia in a calorimeter whose heat capacity (excluding any water) is 480. J/K. The following reaction occurs when the two solutions are mixed.
HCl(aq) + NHg(aq) <=> NH₄Cl(aq)
The temperature increase is 2.34
Calculate ∆H per mole of HCl and NH₃ reacted.
a. -1.96 KJ/mol
b. 485 kJ/mol
c. -154 kJ/mol
d. 1.96 KJ/mol
e. 154 kJ/mol
