Calculating the value of the equilibrium constant for a reaction is helpful when determining the amount of each substance formed at equilibrium as a ratio of each other. The constant doesn't depend on the initial concentrations of the reactants and products, as the same ratio will always be ...
values will be reported as having no units. Sample Problem: Calculating an Equilibrium Constant Equilibrium occurs when nitrogen monoxide gas reacts with oxygen gas to form nitrogen dioxide gas. At equilibrium at 230°C, the concentrations are measured to be [NO] = 0.0542 M, [O2] = 0.127 M...
If the value for the equilibrium constant is small, then the equilibrium favors the reaction to the left, and there are more reactants than products. If the value of Kcapproaches zero, the reaction may be considered not to occur. If the values for the equilibrium constant for the forward ...
The equilibrium constant of the activity coefficients Kγ=∏j=1Sγjνj can be calculated by means of a liquid activity model (see Chapter 6). The case of heterogeneous equilibrium is more difficult, but less frequent in practice. Supplementary material may be found in more specialised books on...
logK=0.36V⋅20.0591 Step 5: Calculate logKCalculating logK: logK=0.720.0591≈12.182 Step 6: Calculate KTo find K, we take the antilog of logK: K=1012.182≈1.596×1012 Final AnswerThus, the equilibrium constant K for the reaction is approximately: K≈1.596×1012 --- Show More ...

Example Problem 1 - Calculating the Equilibrium Constant from the Standard Cell Potential The standard cell potential is provided for the following chemical reaction, and the two half-reactions are shown below. What is the equilibrium constant for this reaction?
The chief problem with supply-demand analysis is that it requires a strict ceteris-paribus assumption, so that everything but the price and the quantity of the good under analysis remains constant. For many reasons, that assumption can’t literally be true. If the price of the good rises (...
