WebAlso by using other's constant (e.g. Calc_fO2 buffers), we will get the value of the buffer. then how we can calculate the actual fugacity of our samples Cite 1 Recommendation WebJan 30, 2024 · STEP 4: Use the ICE table to calculate concentrations with K a. The expression for K a is written by dividing the concentrations of the products by the concentrations of the reactants. Plugging in the values at equilibrium into the equation for K a gives the following: K a = x 2 0.150 − x = 1.6 × 10 − 2.
