Limestone is predominantly CaCO 3 , which can undergo the reaction CaCO 3 ( s ) → CaO ( s ) + C O 2 ( g ) . We know from experience that this reaction is not spontaneous, yet Δ S for the reaction is positive. How can the second law of thermodynamics explain that this reaction is not spontaneous?

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
Please help me calculate the undiluted samples ppm concentration.
My calculations were 280.11 ppm. Please see if I did my math correctly using the following standard curve.
