The following reaction was carried out in a 3.75 L reaction vessel at 1100 K: C(s)+H2O(g)⇌CO(g)+H2(g) If during the course of th
Kruka [31]

Answer:

Reaction quotient, Q, is 0.44

Explanation:

For the reaction:

C(s)+H₂O(g) ⇌ CO(g)+H₂(g)

Reaction quotient Q, at any course of the reaction, is defined as:

Q = [CO][H₂] / [H₂O]

Concentration of reactants is:

[CO] = 3.20mol / 3.75L = 0.853M

[H₂] = 8.20mol / 3.75L = 2.187M

[H₂O] = 15.9mol / 3.75L = 4.24M

Replacing, Q is:

Q = [0.853][2.187] / [4.24]

<em>Q = 0.44</em>
