can you please show all your steps. I am lost

dure Im the cete andgt EXAMPLE 14.4 EXAMPLE 14.5 Finding Equilibrium Constants Finding Equilibrium Constants from Experimental Partial Pressure Measurements from Experimental Concentration Measurements Consider the following reaction: cog) + 2 H2(g)- CH,OH(g) Consider the following reaction: | Ni(s) + 2 V3+ (aq)--Ni2+(aq) + 2 V2+(aq) A reaction mixture at 400 K initially A chunk of solid nickel is placed into a contained CO and H2 at partial pressures 0.250 mol L- solution of V+ at 298 K. At of 0.750 and 1.000 bar, respectively. At equilibrium the concentration of V was equilibrium, the partial pressure of CO found to be 0.056 mol L-1. What is the value of was found to be 0.295 bar. What is the the equilibrium constant? value of the equilibrium constant?

Explanation / Answer

Ans 14.4

Balanced equation with ICE table

CO + 2H2 = CH3OH

I 0.75 1 -

C - x - 2x +x

E 0.75 - x 1-2x x

At equilibrium

Partial pressure of CO = 0.295 bar

0.75 - x = 0.295

x = 0.455 bar

At equilibrium

Partial pressure of H2 = 1 - 2x = 1 - 2*0.455 = 0.09 bar

Partial pressure of CH3OH = x = 0.455 bar

Equilibrium constant

Kp = pCH3OH /(pH22 pCO)

= 0.455/(0.09*0.09*0.295)

Kp = 190.416
