In the study of Aldehydes, Ketones and Carboxylic Acids, a reaction at standard temperature follows the relationship $PV = nRT$. What happens to the system if the concentration of reactants is doubled?
A
The rate constant doubles.
B
The equilibrium shifts to the right, favoring products.
C
The Gibbs free energy $\Delta G$ becomes zero.
D
The activation energy $E_a$ is halved.
Explanation
According to Le Chatelier's principle and equations like $PV = nRT$ in Aldehydes, Ketones and Carboxylic Acids, increasing reactant concentration favors product formation.
Detailed Solution
In Aldehydes, Ketones and Carboxylic Acids, the reaction quotient $Q$ decreases when reactant concentration increases. Based on $PV = nRT$, the system drives forward to restore equilibrium.
