Question

Transcribed Image Text:a.) C+ 2H2 = CH4
From the equations:
1. С + О23D СО2
AH = -393.51 kJ
2. H2 + % O2 = H20
AH = -285.83 kJ
3. CH4 + 202 = CO2 +H2O
AH = -890.37 kJ
b.) 2N203 = 2N2 + 302
From the equations:
1. N203= NO + NO2
AH = 39.7 kJ
2. ½ N2 + ½ O2 = NO
AH = 90.4 kJ
3. ½ N2 + O2 = NO2
AH = 33.8 kJ
