If kc = 0.143 at 25°c for this reaction, predict the direction in which the system will shift if the initial concentrations of c6h12 and mcp are 0.400 m and 0.300 m, respectively. the system

The equation is as follows:
Cyclohexane (C6H12) ⇔ Methyl cyclopentane (C6H12)
The equilibrium constant Kc = 0.143 >>> (1)
Qc is the reaction quotient 
where; If Q = K >>>> No shift left or right >>> (2)
Q > K >>>> Reaction shifts left >>> (3)
Q < K >>>> Reaction shifts right >>> (4) 
And in our equation; Q = 0.3 / 0.4 = 0.75 >>> (5) 
From (1), (3) and (5), Q > Kc 
∴ the reaction shifts left

About 8 gallons of fuel will be used. (8.08)
