Silylene (SiH2) is а key intermediаte in the thermаl decоmpоsitiоn of silicon hydrides such as silane (SiH4) and disilane (Si2H6). H. K. Moffat et al. (J. Phys. Chem. 95,145(1991) report ∆f H0 (SiH2) = +274 kJ mol-1. Given that ∆f H0 (SiH4) = +34.3 kJ mol-1 and ∆fH0 (Si2H6) = +80.3 kJ mol-1. What is the standard enthalpy change of the following reaction? SiH4(g) ⟶ SiH2 (g) + H2(g)
