Calculate the mean heat capacity, Chemistry

Assignment Help:

a) Calculate the energy required to heat 1kg of CO₂ from 400^oC to 600^oC at a constant pressure of 1atm using:-

i) The mean heat capacity data given below

ii) The heat capacity function:-

Cp = 6.393 + 10.1 x 10-3T - 3.405 x 10-6 T2

Where Cp is in cal/mol K and T is in K.

b) It is desired to calculate the standard hear of the reaction of:-

CH₃Cl (g) + KOH (g) _ CH3OH (l) + KCl (s) (A)

Standard heats of formation for CH3Cl (g) and CH3OH (l) are not available but the data

available does include the standard heats of combustion of CH₃Cl (g) and CH₃OH (l). What

other physical data is required to find the heat of reaction (A)?

Information:

Mean Heat Capacity of CO₂ (cal/mol oC)

Reference Temperature: 0^_oC; Pressure 1 atm

^oC cal/mol ^oC

0 8.595

200 9.590

400 10.360

600 10.965
