The following reaction was carried out in a 3.25 L reaction vessel at 1100 K:
kipiarov [429]

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,

C(s)+H_2O(g)\rightarrow CO(g)+H_2(g)

The expression for reaction quotient will be :

Q=\frac{[CO][H_2]}{[H_2O]}

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 H_2O,CO\text{ and }H_2

\text{Concentration of }H_2O=\frac{\text{Moles of }H_2O}{\text{Volume of solution}}=\frac{13.3mol}{3.25L}=4.09M

and,

\text{Concentration of }CO=\frac{\text{Moles of }CO}{\text{Volume of solution}}=\frac{3.40mol}{3.25L}=1.05M

and,

\text{Concentration of }H_2=\frac{\text{Moles of }H_2}{\text{Volume of solution}}=\frac{6.30mol}{3.25L}=1.94M

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

Q=\frac{(1.05)\times (1.94)}{(4.09)}=0.498

Thus, the value of reaction quotient Q is, 0.498

I think the correct answer from the choices listed above is option A. It is by the process of photosynthesis that would help counteract with human interactions. The carbon dioxide emitted by human activities can be used by this process to produce more oxygen.
