Calculate the ΔGr0 of the following reaction and state whether is it spontaneous at standard temperature or not. (You will need table B-12 in your CRG)
2HCl(aq) + Ca(OH)2(s) → CaCl2(s) +2H2O(l)

-6.5 kJ, yes

-61.5 kJ, no

6.5 kJ, no

61.5 kJ, no

-61.5 kJ, yes

Find the ΔHr0 for the reaction :
2HCl(aq) + Ca(OH)2(s) → CaCl2(s) + 2H2O(l)

ΔHr0=+125.7kJ

ΔHr0=-47.1kJ

ΔHr0=-140.0kJ

ΔHr0=+105.8kJ

ΔHr0=-45.3kJ

Solve the problem: (You will need Table B-12 in your CRG)
You are conducting a calorimetry experiment using a calorimeter with 500mL of water in its outer chamber to determine the enthalpy of reaction of a chemical reaction. The initial temperature of the water is 25°C. After the reaction, the temperature of the water is 62.8°C. Disregarding any heat loss to the walls of the container, calculate the ΔHr0. The specific heat of water is 4.18J/(g•K).

ΔHr0=79.0kJ

ΔHr0=45.3kJ

ΔHr0=25.7kJ

ΔHr0=-140.0kJ

ΔHr0=105.8kJ
