Phosphine, PH3PH3 , is a colorless, toxic gas that is used in the production of semiconductors as well as in the farming industry. When heated, phosphine decomposes into phosphorus and hydrogen gases. 4PH3(g)⟶P4(g)+6H2(g)4PH3(g)⟶P4(g)+6 H2(g) This decomposition is first order with respect to phosphine, and has a half‑life of 35.0 s at 953 K. Calculate the partial pressure of hydrogen gas that is present after 79.4 s79.4 s if a 4.60 L4.60 L vessel containing 2.57 atm2.57 atm of phosphine gas is heated to 953 K
