Answer all parts as fully as you can, just as if it were a realexam
(a) State the First Law of Thermodynamics
(b) Explain the difference between heat and work
(c) Explain why the heat capacity of a gas is different atconstant pressure than at constant volume
(d) Explain what is meant by thestandard enthalpy of formation of a compound
(e) Explain what is meant by the standard enthalpy of combustionof a compound
(f) Use information in the Data section of the textbook tocalculate the standard enthalpy at 298K of the reaction N2(g) +3H2(g) → 2NH3(g)
(g) Use your result from (f) to determine the change inenthalpy
(a) when 1 tonne (103 kg) of N2 is consumed
(b) when 1 tonne of NH3 is formed
