33. Solution to Chemistry Problem

13. For the reaction given in Table 1.3:
1) calculate the heat of reaction based on the known values ​​of standard heats of formation of the starting materials and reaction products;
2) determine ΔН based on the assumption:
a) Δс=0;
b) ) Δс=const;
c) ) Δс=f(T).
3) determine ΔS298 and ΔSт for the reaction;
4) calculate the value of ΔG298 and ΔGт and draw a conclusion about the direction of the reaction under standard conditions and at temperature T
Thermodynamic characteristics of the substances are given in Table 1.4
Reaction equation T,K
2SO2(g) O2(g)=2SO3(g) 700
