Answer to Question #128593 in General Chemistry for A

Question

Good day,

The following reaction was carried out in a 2.50 L reaction vessel at 1100 K:
C(s)+H2O(g)⇌CO(g)+H2(g)
If during the course of the reaction, the vessel is found to contain 10.0 mol of C, 12.3 mol of H2O, 3.40 mol of CO, and 7.80 mol of H2, what is the reaction quotient Q

Thank you so much

Answer 1

Concentration for C is 10.0mol/2.50L=4.00 M, for H2O is 12.3mol/2.50L=4.92M, for CO is 3.40mol/2.50L=1.36M, and for H2 is 7.80mol/2.50L=3.12M

Thus, Q=(1.36*3.12)/(4.00*4.92)=0.216
