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?
