Solve the following modified entropy optimization problem. For ease of solution you can solve the problem ignoring the non-negativity constraints on p and q and then verify that they are satisfied.

min p log p +2qlog q

subject to p+q = 1

p,q >=0

min p log p +2qlog q

subject to p+q = 1

p,q >=0

Consider the following problem related to entropy maximisation in information theory. For ease of solution you can solve the problem ignoring the non-negativity constraints on p and q and then verify that they are satisfied.

min p log P + q log q

subject to p+q =1

p,q.>=0

i. Solve the primal problem directly

ii. Obtain the dual problem and solve it. Verify it gives the same answer as the primal problem.

iii. By doing an internet search or looking up textbooks, explain why this problem would be

called an “entropy maximisation” problem.

A piston-cylinder device contains 1.38 kg of refrigerant-134a at -10 oC. The piston that is free to move has a mass of 16 kg and a diameter of 11.18 cm. The local atmospheric pressure is 84 kPa. Now, heat is transferred to refrigerant-134a until the temperature is 90 oC. Determine (a) the final pressure (kPa), (b) the change in the volume of the cylinder (m3), and (c) the change in the enthalpy of the refrigerant-134a (kJ/g).

Submit your answer by mutiplying the answers (a)*(b)*(c) = _______.

In the selective oxidation of isobutylene to dimethyl ketone using a MoO3/U308/SiO2 catalyst it is thought that each reactant utilizes different catalytic sites. The reaction rate is controlled by surface reaction between the two adsorbed species. Postulate a sequence of elementary steps and derive the LH rate equation; sketch the rate versus pressure of isobutylene curve assuming the 0 2 pressure is large. Compare this plot to the case where both reactants compete for the same sites.
