Problem

State the effect of increasing the pressure of the following systems in dynamic equilibrium and give a reason for your answers: (1) PCl3(g)+Cl2(g)⇌PCl5(g)\text{PCl}_3(\text{g}) + \text{Cl}_2(\text{g}) \rightleftharpoons \text{PCl}_5(\text{g}) (2) 2NH3(g)⇌N2(g)+3H2(g)2\text{NH}_3(\text{g}) \rightleftharpoons \text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) (3) H2(g)+I2(g)⇌2HI(g)\text{H}_2(\text{g}) + \text{I}_2(\text{g}) \rightleftharpoons 2\text{HI}(\text{g}) (4) CaCO3(s)⇌CaO(s)+CO2(g)\text{CaCO}_3(\text{s}) \rightleftharpoons \text{CaO}(\text{s}) + \text{CO}_2(\text{g}) (5) H2O(l)⇌H2O(g)\text{H}_2\text{O}(\text{l}) \rightleftharpoons \text{H}_2\text{O}(\text{g})
