Answer : The value of reaction quotient Q is, 0.498
Explanation:
Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.
The given balanced chemical reaction is,

The expression for reaction quotient will be :
![Q=\frac{[CO][H_2]}{[H_2O]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BCO%5D%5BH_2%5D%7D%7B%5BH_2O%5D%7D)
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now we have to calculate the concentration of 

and,

and,

Now put all the given values in the above expression, we get:

Thus, the value of reaction quotient Q is, 0.498
