At 1045 K the partial pressures of an equilibrium mixture of H2O(g), H2(g), and O2(g) are 0.0400, 0.00450, and 0.00300 atm, respectively. Calculate the value of the equilibrium constant Kp at 1045 K.

the answer is b & c i believe : )

the answers would be

the first one and the second one

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
