1 mole of P4 gives 4 moles of PH3 as per balanced reaction
Hence Blank 1 will be 1 and Blank 2 will be 4
6 mole of H2 gives 4 moles of PH3 as per balanced reaction
Hence Blank 3 will be 6 and Blank 4 will be 4
1 mole of P4 reacts with 6 moles of H2 as per balanced reaction
Hence Blank 5 will be 1 and Blank 6 will be 6

Consider the reaction 4 PH3(g) → P4(g) + 6 H2(g). If, in a certain experiment, over a specific time period, 0.0045 mole of PH3 is consumed in a 1.7-L container during each second of the reaction, what are the rates of production of P4 and H2 in this experiment? P4 mol L−1 s−1 H2 mol L−1 s−1
The decomposition of phosphine, PH3, follows first-order kinetics: 4 PH3(g) → P4(g) + 6 H2(g) Calculate the activation energy, Eq, in kJ/mol for the reaction, given that the rate constant k (at 25 °C) = 0.00852 s 1 and k (at 50 °C) = 0.756 s 1. 231 kJ/mol 144 kJ/mol O 56.5 kJ/mol О 99.3 kJ/mol O 111 kJ/mol
8. The balanced equation P4 (s) + 6H2 (g) --> 4PH3 tells us that 2 mol H2 a. reacts with 1 mol 4 b. produces 4 mol PH3 c. cannot react with phosphorus d. produces 2 mol PH3 e. reacts with 2 mol P4 idk y i cant seem to get the answer from the choices above?
For the gas phase decomposition of phosphine at 120 °C 4 PH3(g)P4(g) + 6 H2(g) the average rate of disappearance of PH3 over the time period from t = 0 s to t = 27 s is found to be 2.63×10-4 M s-1. The average rate of formation of H2 over the same time period is________ M s-1.
The gas phase decomposition of phosphine at 120 °C PH3(g)1/4 P4(g) + 3/2 H2(g) is first order in PH3 with a rate constant of 1.80×10-2 s-1. If the initial concentration of PH3 is 5.86×10-2 M, the concentration of PH3 will be 1.43×10-2 M after s have passed.
