Calculate δs0 for the following processes:
a.) heating 1 mol of benzene(liquid) from 298k to 353 k at 1 bar pressure, neglecting any t-dependence of cp.
b.) vaporizing the resulting benzene (l) to benzene(g) at its normal boiling point of 353 k, at 1 bar pressure. note: its latent heat of vaporization at 353 k is 30.8 kj/mol.
c.) the total process of steps (a) and (b) both.

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
