(a) Consider the temperature dependent heat capacity of O2(g)
given in the Resource
section of your textbook (29.355J/Kmol). What is the heat absorbed
at constant pressure when 1 mole
of O2(g) is heated from 0o C to 500oC? (Hint: Integrate!)
(b) Construct a plot of Cp,m (for O2(g)) vs. T and plot it
between 0 and 500
oC. What is the % error if you had used a temperature-independent
heat capacity for part (a)?

From information in the “Data section” of your textbook, calculate the standard
Gibbs free energy and the equilibrium constant at (a) 25°C and (b) 50°C for the reaction
CH4(g) + 3 Cl2(g) <--> CHCl3(l) + 3 HCl (g).
Assume that the reactionenthalpy isindependent of temperature.
ΔG°f (CHCl3, l) =-71.8 kJ/mol, ΔH°f(CHCl3, l) =‐132.2 kJ/mol
Which extra DATA can i provide from the textbook. What values should I look for?
