At 300°C and at a pressure of 0 – 60 atm, the Joule-Thomson coefficient of N2(g) can be represented by the equation ?=0.0142−2.60×10−4? Assuming this equation to be temperature-independent near 300 °C, find the temperature drop which may be expected on Joule-Thomson expansion of the gas from 60 to 20 atm

When a certain freon used in refrigeration was expanded adiabatically from an initial pressure of 32 atm and 0°C to a final pressure of 1.00 atm, the temperature fell by 22 K. Calculate the Joule-Thomson coefficients, μ, at 0°C, assuming it remains constant over this temperature range.

The equilibrium constant for a system at chemical equilibrium at 318 oC is 3.4 x 10-3.  Calculate the Gibbs free-energy change, deltaGo, for the system at 318 oC.Enter your answer here: kJ/mol

A chemical engineer is studying the two reactions shown in the table below. In each case, he fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 133.0 °C and constant total pressure. Then, he measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium. 2CH₂OH(g) + 30₂(g) → 2CO₂(g) + 4H₂O(g) 4H₂PO4(s) P4O10 (s) + 6H₂0 (1) AH-1353. kJ AS = -3331.
