The reaction between phosphorus (P_(4)) and hydrogen (H_(2)) can result in the formation of phosphine (PH_(3)) as shown : P_(4)(s)+6H_(2)(g)hArr 4PH_(3)(g) The graph shows the change in concentration of hydrogen for this reaction in which the system was distrubed after four hours. Whichof the following could explain the change in hydrogen concentration at time = 4 hours?
