1. а) (6 pоints) A nаturаl gas pоwer plant with a generating capacity оf 2,000 megawatts operates 50% of the time to accommodate periods of high power demand. How many metric tonnes (=1000 kg) of CO2 will be added to the atmosphere each year. Assume a natural gas power plant has an efficiency of 60% for converting chemical energy to electrical energy. Assume that natural gas is pure CH4 and that the enthalpy of combustion is CH4 (g) + 2O2(g)
