In a chemical plant, hydrogen gas with a flow rate of 0.1 is cooled from 500 K to 13 K with nitrogen gas in a countercurrent heat exchanger. Nitrogen gas enters the heat exchanger at 300K and exits at 323K. During this process, heat is released to the environment at a rate of 36kJ/s. Assuming that the gas behaves ideally and its temperature to the environment is 300K, calculate the entropy formation rate for this process.
