C(s) + 2Cl2(g) -> CCl4(l) ∆= -106.4 kJ What is the molar enthalpy for chlorine?
To find the molar enthalpy for chlorine, we need to determine the change in enthalpy per mole of chlorine.
The balanced equation for the given reaction is:
C(s) + 2Cl2(g) -> CCl4(l)
From the balanced equation, we can see that for every 2 moles of Cl2, we produce 1 mole of CCl4.
The change in enthalpy for the reaction is given as ∆H = -106.4 kJ.
Therefore, the molar enthalpy for chlorine can be calculated as follows:
Molar enthalpy of Cl2 = ∆H / coefficient of Cl2
Molar enthalpy of Cl2 = -106.4 kJ / 2 = -53.2 kJ/mol
Therefore, the molar enthalpy for chlorine is -53.2 kJ/mol.
