The reaction 2NO(g) + Cl2 (g) --> 2NOCl(g) is carried out in a closed vessel. If the partial pressure of {NO} is decreasing at the rate of 27 torr/min, what is the rate of change of the total pressure of the vessel?
What is the system? What is the surrounding? In what direction does the heat flow? Is the process endothermic or exothermic?
