Question 2 (1 point)
Consider the following reactions
i) $C_{(s)} + 2H_{2(g)} \rightarrow CH_{4(g)}$ $\Delta H = -74.8 \, kJ$
ii) $C_{(s)} + 2Cl_{2(g)} \rightarrow CCl_{4(l)}$ $\Delta H = -106.4 \, kJ$
iii) $\frac{1}{2}H_{2(g)} + \frac{1}{2}Cl_{2(g)} \rightarrow HCl_{(g)}$ $\Delta H = -92.3 \, kJ$
The enthalpy change for the reaction $CH_{4(g)} + 4Cl_{2(g)} \rightarrow CCl_{4(l)} + 4HCl_{(g)}$ is
-400.8 kJ
-216.2 kJ
-273.5 kJ
-123.9 kJ
