I need pressure and Kp please... a The gas arsine, AsHz, decomposes as follows: 2AsH3(g) = 2As(s) + 3H2(g) In an experiment at a certain temperature, pure AsH3(g) was placed in an empty, rigid, sealed flask at a pressure of 385.0 torr. After 48 hours the pressure in the flask was observed to be constant at 482.0 torr. Calculate the equilibrium pressure of H2(g). Pressure = atm Calculate K, for this reaction. K,=
