I values chemistry
Webrange of values = highest value - lowest value = 23.91 - 23.24 = 0.67 The range of values is closer to 1 than it is to 0 so we would decide that the student's measurements are NOT precise, they are imprecise. Conclusion: the student's temperature readings are neither accurate nor precise. WebJan 26, 2024 · The equilibrium constant is the value of the reaction quotient that is calculated from the expression for chemical equilibrium. It depends on the ionic strength and temperature and is independent of the concentrations of reactants and products in a solution. Calculating the Equilibrium Constant For the following chemical reaction:

Ka = [Mg 2+] [Cl –] 2 / [MgCl 2 ] Thus, we can quickly determine the Ka value if the molarity is known. Ka from pH. We can use pH to determine the Ka value. pH is a standard used to measure the hydrogen ion concentration. pH = – log [H +] We can rewrite it as, [H +] = 10 -pH.
