0.175 g of solid PCI, is sealed inside a 100. mL container from which all the air has been removed. The container is heated to 250 °C. At this temperature, the entire sample vaporizes and the resulting gaseous PCls undergoes the following reaction. PC15 (9) = PC13(9) + C12(g) After the reaction reaches equilibrium, the total pressure inside the...
