Solved: Coal can be used to generate hydrogen gas (a potential fuel) by this endothermic
Chapter 15, Problem 76P(choose chapter or problem)
Coal can be used to generate hydrogen gas (a potential fuel) by this endothermic reaction.
\(\mathrm{C}(\mathrm{s})+\mathrm{H}_{2} \mathrm{O}(g) \rightleftharpoons \mathrm{CO}(g)+\mathrm{H}_{2}(g)\)
If this reaction mixture is at equilibrium, predict the effect (shift right, shift left, or no effect) of these changes.
(a) adding more \(\mathrm{C}\) to the reaction mixture
(b) adding more \(\mathrm{H}_{2} \mathrm{O}(g)\) to the reaction mixture
(c) raising the temperature of the reaction mixture
(d) increasing the volume of the reaction mixture
(e) adding a catalyst to the reaction mixture

Step by Step Solution
Step 1 of 5
(a)
According to Le Chatelier’s principle “When a chemical system at equilibrium is disturbed, the system shifts in a direction that minimizes the disturbance.
The given reaction is as follows.
The given – Adding more “C” to the reaction mixture.
The Carbon element is present in the solid state and it is one of the reactants in the given reaction mixture. Solid state compounds don't affect the equilibrium of the reaction.
Therefore, there is no effect for adding more “C” to the reaction mixture.
