Question

Determine the Delta H degree for the production of coal gas

2C (s) + 2 H20 (g) ------> CH4 (g) + CO2 (g)

Using:

C(s) + H2O (g) ----> CO (g) + H2 (g) Delta H = 131.3 kJ

CO (g) + H2O (g) ----> CO2 (g) + H2 (g) Delta H= -41.2 kJ

CH4 (g) + H2O (g) ----> CO (g) + 3 H2 (g) Delta H =206.1 kJ

Part B:

Maltose is hydrolyzed to glucose, calculate the standard enthalapy of change delta H for the reaction:

C12H22O11 (aq) + H20 (l) ----> 2C6H12O6 (aq)

Species Delta f H kJ/mol

H2O (l) -285.830

H2O (g) -241.826

C12H22O11 (aq) -2238.3

C6H12O6 (aq) -1263.1

Explanation / Answer

Determine the Delta H degree for the production of coal gas

2C (s) + 2 H20 (g) ------> CH4 (g) + CO2 (g)

Using:

C(s) + H2O (g) ----> CO (g) + H2 (g) Delta H = 131.3 kJ
