Chapter 5, Problem 69E

Using the data in Appendix G, calculate the standard enthalpy change for each of the following reactions:

(a) $\text{Si}\left(s\right)+2{\text{F}}_2\left(g\right)\to {\text{SiF}}_4\left(g\right)$

(b) $2\text{C}\left(s\right)+2{\text{H}}_2\left(g\right)+{\text{O}}_2\left(g\right)\to {\text{CH}}_3{\text{CO}}_2\text{H}\left(l\right)$

(c) ${\text{CH}}_4\left(g\right)+{\text{N}}_2\left(g\right)\to \text{HCN}\left(g\right)+{\text{NH}}_3\left(g\right)$ ;

(d) ${\text{CS}}_2\left(g\right)+3{\text{Cl}}_2\left(g\right)\to {\text{CCl}}_4\left(g\right)+{\text{S}}_2{\text{Cl}}_2\left(g\right)$
