MCQ
The enthalpy changes for the following processes are listedbelow :
| $Cl_2(g) \rightarrow 2Cl(g),$ | $242.3\,kJ\,mol^{-1}$ |
| $I_2(g) \rightarrow 2I(g),$ | $151.0\,kJ\,mol^{-1}$ |
| $ICl(g) \rightarrow I(g)+Cl(g),$ | $211.3\,kJ\,mol^{-1}$ |
| $I_2(s) \rightarrow I_2(g),$ | $62.76\,kJ\,mol^{-1}$ |
Given that the standard states for iodine and chlorine are $I_2(s)$ and $Cl_2(g),$ the standard enthalpy of formation for $ICl(g)$ is : ............... $\mathrm{kJ\,mol}^{-1}$
- ✓$+16.8$
- B$+244.8$
- C$-14.6$
