1. Calculate the heat of hydrogenation of ethane (C2H6) given the following thermochemical equations:
a. 2 C (graphite) + 3 H2 (g) π‘Ί C2H6 (g) ΞHfo = - 84.5 kJ/mol
b. 2 C (graphite) + 2 H2 (g) π‘Ί C2H4 (g) ΞHfo = 52.3 kJ/mol
Reaction of heat of hydrogenation of ethane:
Given that:
Equation .1.
Equation .2.
Now to form the main equation we have to subtract equation 2 from equation 1:
So heat of hydrogenation
