A fuel cell’s thermodynamic voltage change Δ V measure in millivolts is linearly dependent on theoperating temperature T measured in °C. This relationship follows the equation:Δ V =Δ V 0+ SnF TWhere S is the entropy of the system, Δ V 0 is the initial voltage difference, and nF is a constant.a) If the quantity of nF = 193 (J/mV), determine both the initial voltage difference and the entropy of theS and write the equation of the line Δ V (T ).b) Plot the graph of Δ V as a function of T in Excel and copy and paste the graph into Word. Be sure toproperly label the graph and clearly indicate the slope and y-intercept on the graph.T(°C) Δ V (mV )25.0 49.080.0 -28.0

A solar collector system delivers heat to a power plant. It is well known that the thermal collection efficiency hsc of a solar collector diminishes with increasing solar collection output temperature TH , or hsc = A 2 BTH where A and B are known constants. The thermal efficiency of the power plant hth is a fixed fraction of the Carnot thermal efficiency, such that hth = F(1 2 TL/TH) where F is a known constant assumed here independent of temperatures and TL is the condenser temperature, also constant for this problem. Here, the solar collection temperature TH is also taken to be the source temperature for the power plant. (a) At what temperature TH should the solar collector be operated to obtain the maximum overall system efficiency? (b) Develop an expression for the maximum overall system efficiency.
