The combination of coke and steam produces a mixture called coal gas, which can be used as a fuel or as a starting material for other reactions. If we assume coke can be represented by graphite, the equation for the production of coal gas is?
The combination of coke and steam produces a mixture called coal gas, which can be
used as a fuel or as a starting material for other reactions. If we assume coke can be
represented by graphite, the equation for the production of coal gas is
(3) CH (g) H O (g) 3 H (g) CO (g) H 206.1kJ
(2) CO (g) H O (g) CO (g) H (g) H - 41.2 kJ
(1) C(s) H O (g) CO (g) H (g) H 131.3 kJ
standard enthalpies of reaction :
Determine the standard enthalpy change for this reaction from the following
2 C (s) 2 H O (g) CH (g) CO (g)

1 Answer
Explanation:
The equation for the formation of coal gas is
This is our target equation. We must create it from equations (1) - (3).
We start with Equation (1), because it contains
2 × (3):
(2):
-(1):
(4):
