Questions (page 2)

Section A

Q1.

(a) A liquid has 40 (wt%) CH3OH and 60 (wt%) C2H5OH. Calculate the average molecular weight of the liquid.

(b) Discuss 'Autocatalytic' reactions with the help of typical rate concentration curve.

(c) How is the COP of a heat pump related to the COP of a refrigerator?

(d) Calculate the entropy change if 1 kg of water at 303 K is heated to 353 K at 1 bar pressure. The heat capacity of water may be taken as 4.2 kJ/kg K.

(e) What is the standard Gibb's free energy change of a chemical reaction? How is it related to equilibrium constant?

Section A

Q2.

(a) A batch adiabatic reactor at an initial temperature of 373 K is being used for the reaction : A → B. Assume that the heat of reaction is -1 kJ/mol at 373 K and the heat capacity of both A and B to be constant and equal to 50 J/mol K. Calculate the temperature rise for 1 mole of feed and after a conversion of 0.5.

(b) A wet paper pulp contains 75% water. After 100 kg of water is removed in a dryer, it is found that the pulp now is containing 30% water. Calculate the weight of the original pulp.

(c) One mole of methane undergoes complete combustion in a stoichiometric amount of air. Both the reactants and products are in the gas phase. Estimate the mole fraction of water vapour in the product gas.
