Q2. Consider the hydrogenation of ethylene
C2H4 + H2 = C2H6
The heats of combustion and molar entropies for the three gases at 298 K are given by:
C2H4
C2H6
H2
AH comb/kJ mol¹
-1395
-1550
-243
Sº / J K¹ mol-1
220.7
230.4
131.1
The average heat capacity change, ACP, for the reaction over the temperature range 298-1000 K is
10.9 J K¹ mol¹. Using these data, determine:
(a) the standard enthalpy change at 800 K
(b) the standard entropy change at 800 K
(c) the equilibrium constant at 800 K.
