Question

write the equilibrium constant expressions for each of the following chemical reactions. a utch 3. Write the equilibrin L reactants a) CH3OH (g) → CO (g) + 2H2 (g) b) C3H8 (g) + 502 (g) 3CO2 (g) + 4H2O(g) c) N2(g) + O2(g) + 2NO(g) 4. For each of the following values of K, indicate whether the forward reaction, reverse real or neither would be favored. a. Keq = 3.7 x 108 (K>>>1) b. Keq = 4.1 x 10-3(K«<<l) c. Keq = 1.47 (K-1)

Answer 1

3) Equilibrium constants for the following chemical reactions:

a)

CH3OH) = CO) + 2H2(g)

K_c = [CO].[H₂]²/[CH3OH]

b)

CzHgle) + 50248) 3C02(g) + 4H2013)

K_c = [CO₂]^2.[H₂O]⁴/[C₃H₈].[O₂]⁵

c)

N2(e) + O2(8) A 2 NO()

Kc = [NO]²/[N₂].[O₂]

[ ] - used to describes concentration terms

4) a) forward reaction is favored (K > 1)

b) reverse reaction is favored (K < 1)

c) neither forward nor reverse reaction are favored (K = 1)
