Consider the reaction of methane with oxygen: 2CH4 + O2↔ 2CH3OH At equilibrium, the compositions of the components satisfy the relation K=(y_CH3OH^2)/(y_CH4^2 y_O2 ) If you are given the feed compositions (3 mol CH4 and 1 mol O2) and the equilibrium constant K(T), how do you determine the equilibrium compositions?

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
