Yes, the values of the equilibrium constants of all solution are the same. the formula of an equilibrium constant is
is the equilibrium constant is dependent on the number of moles of reactant and number of moles of product (or concentrations of both product and reactant) react in the reaction.
in the above scenario all solution are equilibrium this means the ratio of reactant and product are same then equilibrium constant also same.

Post Lab Questions 1. in a hurry to complete the experiment, the student failed to calibrate the Spectrophotometer. As a result, all absorbance values for the standard solutions that are measured and recorded are too high. How will this affect the following calculations in Part B? a. Will the calculated equilibrium concentrations of FeSCN** be too high, too low, or unaffected? Explain. b. Will the calculated equilibrium constants be too high, too low, or unaffected? Explain. 2. In Part A,...

Hello, I'm in Ap chem and have a lab due tonight. in the lab we had to determine the mole ratio between cucl2 and na2hpo4 which was 1:1. one of the questions asked whether it mattered if the molarities of the two solutions were the same. during the experiment, we made both the solutions with .5M, but could we still determine the ratio if they were different molarities? please provide an explanation because I'm so confused! thank you.
