Web24 jan. 2024 · Now let's repeat the same exercise with a fairly big positive value of ΔG° = +60.0 kJ mol -1. And we will keep the same temperature as before - 373 K. ΔG° = -RT ln K. +60000 = -8.314 x 373 x ln K. This gives ln K = -19.35. Using the e x function on your calculator gives a value for K = 3.96 x 10 -9. That is a tiny value for an equilibrium ...

WebK eq is a number that, under specified conditions, is always the same for a given reaction. If the temperature changes, the equilibrium constant will change. This means that when you quote an equilibrium constant, you must also quote the temperature it was obtained at . WebIf any of the reactants or products are solids or liquids, their concentrations are equal to one because they are pure substances. (see Solubility Product Constant, K sp) The standard example of writing Gas Equilibrium Constants are: aA + bB ⇌ cC + dD. Kc = [C]c[D]d [A]a[B]b. Kp = (C)c(D)d (A)a(B)b.

"WebAcid Base Chemistry. Acid base reactions are reversible and therefore equilibrium reactions. With acid base reactions we focus on the extent to which theACID (reactant) is deprotonated to the conjugate acid (product). Therefore, as the equivalent to the equilibrium constant, we look at the Ka. " - Keq chemistry meaning
