Determination of equilibrium constant keq
WebQc is smaller than KeqQc is equal to KeqQc is larger than Keq. Step 2. (Optional) You may enter your compounds and equation in the boxes if you wish. Step 3. Enter initial … WebIn addition, temperature plays a big role in the determination of the equilibrium constant. For instance, the Keq will change if the temperature changes. If for some reason the room temperature were to shift while performing the experiment, the equilibrium constant could shift creating a higher Keq value than the actual value.
