Many treatment plants use chlorine gas wastewater to kill microorganisms in the liquid before downloading this treated water to the sea. A plant engineer has to keep the pressure of chlorine in the tank below 85.0 atm for the plant to operate under conditions of pressure maxima. How many molecules of Cl2 gas will be present in the tank of 225 gallons to 25 Celcius.
A reaction mechanism involving three steps is shown below. Identify all of the catalysts in the following mechanism.
