Question:

In Example 13-12, we used the van’t Hoff equation to determine the temperature at which for the reaction 2 SO2(g) + O2(g) ⇌ 2 SO3(g). Obtain another estimate of this temperature with data from Appendix D and equations (13.13) and (13.17). Compare your result with that obtained in Example 13-12.

Example 13-12

Use data from Table 13.8 and Figure 13-10 to estimate the temperature at which K = 1.0 x 106 for the reaction

2 SO(g) + O(g) = 2 SO3(g)

Table 13.8

Eq. 13.13

AG =   S (13.13)

Eq. 13.17

A,G-RT In K = (13.17)
