What is the partial pressure of the product related to the total pressure for a constant volume system? (Where pR is the partial pressure of the product, pR0 is the initial partial pressure of the product, P is the total pressure, P0 is the initial pressure of reaction mixture, r is the stoichiometry of the product and n is the difference between the number of moles of the product and the number of moles of the reactant)

pR = pR0 ( frac{r}{ n} ) (P P0)

pR = pR0 + ( frac{r}{ n} ) (P P0)
