Question:

(A) Estimate the temperature at which K = 5.8 x 10-2 for the reaction in Example 13-12. Use data from Table 13.8 and Figure 13-10.

(B) What is the value of Kp for the reaction 2 SO2(g) + O2(g) Δ 2 SO3(g) at 235 °C? Use data from Table 13.8, Figure 13-10, and the van’t Hoff equation (13.25).

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 SO2(g) + O2(g) = 2 SO3(g)

Table 13.8
