Question

Carbon disulfide is a foul-smelling solvent that dissolves
sulfur and other nonpolar substances. It can be made by
heating sulfur in an atmosphere of methane:
4 CH4(g) + S8(s) (equilibrium arrows) 4 CS2(g) +8 H2(g)

Starting with the appropriate data in Appendix 4, calculate
the values of Kp for the reaction at 25°C and 500°C.

(Appendix 4: CH4= -50720J, S8= 0, CS2= 65100J, H2=0

Step 1

The balanced chemical reaction is given below.

Step 2

Heat of the reaction can be calculated as shown below.

Step 3

Suppose the change in enthalpy of the reaction is 1219.1 J/K. The chang... help_outlineImage Transcriptionclose298 K At T AG AH TAS an 463280J-(298K x1219.1J/ K) 99988.2J/mol. The relationship between Gibb's free energy and equilibrium constant of a reaction is given below AG'-2.303 RT log K Thus the value of equilibrium constant at T 298 K is given below.
