... At equilibrium, the number of moles of SO3 present in the reaction vessel will always be the same as the number of moles of SO2 present, regardless of the temperature. Changing the volume of the vessel changes the amount of oxygen in the system. Changing the temperature changes the amount of oxygen ...

... 1. State in your own terms what is the first law of thermodynamics, a closed system, an isolated system, surroundings, heat, work, and energy. The first law of thermodynamics is the conservation of energy law. Energy cannot be created or destroyed; it can be only converted from one form into another ...

... 5. First Principle of Thermodynamics Although we are discuss only dissipative cycles, the equivalence of heat and work applies to every cyclic process – heat engines function by converting heat into work during an indefinite series of cycles. But what about non-cyclic transformations? The principle ...
