Transcribed Image Text:The heat capacities for each
of the substances involved
for a particular reaction are
given below. The enthalpy
change for the same reaction
at 298 Kelvin is -282.987
KJ/mole. From these, answer
the questions that follow.
Temperature-Dependence of the heat
capacities of the Substances for the
given reaction
+ (1/2)02(9) → CO2(9)
For the gaseous reaction; CO
the heat capacities are:
Cp°co
P(g)
26.86 + 6.97 x10-3 T -
8.20 x10-7 T2
%3D
Cp°o2
25.72 + 12.98 x10-3 T -
38.60 x10-7 T²
%3D
Cp°co2
26.00 + 43.50 x10-3 T
148.32 x10-7 T²
%3D
What would be the overall
enthalpy change at 1,000 Kelvin
(AH @ 1000K, in KJ)?
