Methanol CH3OH is a promising fuel that can be synthesized f

Methanol, CH3OH, is a promising fuel that can be synthesized from carbon monoxide and hydrogen according to the equation CO(g) + 2H2(g) CH3OH(g)

For this reaction at 219 °C, KP = 0.011

Calculate the value of K_c at this temperature.

Solution

Kp = Kc (RT) ^n

R = 0.08206 L atm / mol. k

T = 219 +273.15 => 492.15 K

n = number of gaseous products - number of gaseous reactants

n = 1 - 3 => -2

Kc = 0.011 / (0.08206*492.15)^-2

Kc = 17.94
