What is the reaction quotient (Q) of:
C(graphite)+ CO2(g) = 2 CO (g)
To find the reaction quotient (Q) for the given chemical reaction, you need to compare the concentrations or partial pressures of the reactants and products at a specific point in the reaction. The reaction quotient is calculated by writing an expression using the molar concentrations (or partial pressures) of the reactants and products raised to the power of their respective stoichiometric coefficients.
Let's break down the given chemical reaction:
C(graphite) + CO2(g) → 2 CO(g)
The reaction quotient (Q) for this reaction can be expressed as:
Q = [CO]² / [C][CO2]
Here, [CO] represents the molar concentration of CO, [C] represents the molar concentration of C, and [CO2] represents the molar concentration of CO2.
Note that the concentrations of the reactants and products should be taken at the same point in the reaction to calculate Q. It could be at the beginning (initial concentrations), during the reaction (instantaneous concentrations), or at equilibrium (equilibrium concentrations).
By plugging in the appropriate concentrations into the equation, you can calculate the reaction quotient (Q) for a given point in the reaction.
