Molar mass of phosphorus trichloride = 137.33 g/mol. Putting values in equation 1, we get: The chemical reaction of phosphorus trichloride with water follows the equation: As, water is present in excess. It is considered as excess reagent. Phosphorus trichloride is considered as a limiting reagent because it limits the formation of product. However, the reaction products consist of a mixture of several gases other than hydrogen, such as methane, carbon dioxide and monoxide, sulfur and nitrogen compounds. The reaction of metals with water to produce hydrogen has recently been extensively investigated.
