the equilibrium constant at 250C for the equation PCl5 PCl3 is kp 4.5 x 10^3 bar calculate value of grxn at 250C in which direction is reaction spontaneous when pcl3 cl2 standard conditions

-36.6 kJ·mol⁻¹  

Explanation:

1. Calculate ΔG

T = (250 + 273.15) K = 523.15 K

2. Direction of spontaneity

ΔG is negative, so the reaction is spontaneous in the forward direction.

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.
