This is accomplished by the water gas reaction: C (s) + H2O (g)      →      CO (g) + H2 (g) What is the entropy value for the water gas reaction shown above?   A. – 268 kJ/mol B. – 134 kJ/mol C. 0 kJ/mol D. +134 kJ/mol

Problem

Coal is a major source of energy that can be converted from its solid, raw form to a gaseous phase of fuel. This is accomplished by the water gas reaction:

C (s) + H2O (g)      →      CO (g) + H2 (g)

What is the entropy value for the water gas reaction shown above?

 

A. – 268 kJ/mol

B. – 134 kJ/mol

C. 0 kJ/mol

D. +134 kJ/mol
