Total pressure refers to the sum of all partial pressures exerted by different gases present within a system or reaction vessel. It represents the combined force that all gases collectively exert on their surroundings.
Partial pressure refers to the pressure exerted by an individual component (such as a specific gas) within a mixture of gases. It represents their contribution toward the total pressure.
Equilibrium refers to a state in which the forward and reverse reactions occur at equal rates, resulting in no overall change in the concentrations of reactants and products.
Reaction vessel: A reaction vessel is a container in which chemical reactions take place. It can be used to control temperature, pressure, and other variables during the reaction.
