I may be regarded as a student who knowingly but it was not a problem because every person has their own opinion. I know that there is misconception of chemical equilibrium in the material from a professor who may have been a little older but his passion for teaching is still like a young man who had just received a civil servant sispil.
Let's start where the misconception of this material?
1. Equilibrium constant equation can not be derived from chemical kinetics, but must be derived from thermodynamics. Why like that? Now we review the material before chemical kinetics. reaction rate can be determined using the formula:
Where p and q are the reaction order. The teachers usually sanat emphasize that p and q are the order of the reaction and the reaction order can not be obtained from the coefficient reactan, but through experiments.
When the material enters the chemical equilibrium teachers say very loudly that the equilibrium can occur if the forward reaction rate equal to the rate of back reaction.
Then formulate that kestimbangan constant is the product of the concentration-raised product concentration divided by the product of their coefficient of concentration of reactants raised to their coefficients.
Is not this is not consistent ?????
2. The formula must first be taught the concentration equilibrium constant Kc, after which the new states of Kp and the relationship between Kc and Kp.
3. Teachers can not explain why if the temperature changes of Kp and Kc prices can change too?
But fortunately as yet no students who ask that question?
Then how is that supposed to be delivered?
1. That the formula of equilibrium constant can only be derived through the thermodynamic equation of state of equilibrium will be reached when price changes in Gibbs free energy equals zero. Let us follow the discussion follows:
