Question 60

Multiple Choice

Calculate the Δ\Delta H °\degree rxn for the following reaction. ( Δ\Delta H °\degree f [SiO2(s) ] = -910.9 kJ/mol; Δ\Delta H °\degree f [SiCl4(g) ] = -657.0 kJ/mol; Δ\Delta H °\degree f [HCl(g) ] = -92.3 kJ/mol; Δ\Delta H °\degree f [H2O (g) ] = -241.8 kJ/mol)  Calculate the  \Delta H \degree <sub>rxn</sub> for the following reaction. ( \Delta H \degree <sub>f</sub> [SiO<sub>2</sub>(s) ] = -910.9 kJ/mol;  \Delta H \degree <sub>f</sub> [SiCl<sub>4</sub>(g) ] = -657.0 kJ/mol;  \Delta H \degree <sub>f</sub> [HCl(g) ] = -92.3 kJ/mol;  \Delta H \degree <sub>f</sub> [H<sub>2</sub>O (g) ] = -241.8 kJ/mol)    A)  -139.5 kJ B)  -137.4 kJ C)  -104.4 kJ D)  104.4 kJ E)  139.5 kJ
