Add combinations of the following thermochemical equations to determine the enthalphy of the target
reaction
Reaction 1:
CH4(g) + 202(g) → CO2(g)+2H20(1)
A H = -890.3 kJ mol1
Reaction 2: C2H4(g) + H2(g) →
C2H6(g)
A H° = -136.3 kJ mol1
Reaction 3: 2H2(g) + O2(g) → 2H,0(1)
A H° = -571.6 kJ mol1
Reaction 4: 2C2H6(g) + 702(g) + 4CO2(g)+6H20(1) A H° = -3120.8 kJ mol1
arget reaction: 2CH4(g) C2H4(g)+ 2H2(g)
A H° =
kJ mol1
