In a chemical reaction,4 mol of nitrogen monoxide(NO) and 2.5mol of Oxygen(O2) are being mixed togethere in a container with a volume of 1L to produce Nitrogen dioxide (NO2).If the Kc(Equilibrium constant) for this reaction in 0.001.
If the enthalpy of the above reaction is +49kJ/mol.Predict the outcome of the reaction
The equilibrium constant (Kc) is given by:
Kc = [NO2] / ([NO]^2[O2])
Since the initial concentrations of NO and O2 are 4 mol and 2.5 mol respectively, the initial concentration of NO2 is 0 mol.
Therefore, the reaction will proceed in the forward direction to achieve equilibrium. The equilibrium concentration of NO2 will increase, while the concentrations of NO and O2 will decrease to satisfy the equilibrium constant.
The positive enthalpy (+49 kJ/mol) indicates that the reaction is endothermic, meaning it requires energy to proceed. As a result, the reaction favors the formation of NO2 at higher temperatures.
