Help using units throughout the equations please.

An ideal gas in a piston-cylinder assembly undergoes a totally reversible Carnot cycle.

The isothermal compression occurs at 330 K from 100 kPa to 140 kPa while discharging 880 kJ of heat. The thermal efficiency is 45%.

a) What is the temperature of the isothermal expansion, in K?

b) What is the amount of heat transferred in during the isothermal expansion, in kJ?

c) In a real power cycle, would you expect the actual thermal efficiency to be above, below, or the same as stated in the problem?

d) A technician measures performance data and reports that while the temperatures match the model, the actual heat discharge is 870 kJ and the actual heat received is 1900 kJ. Is this possible?
