For a reaction involving only gases at 25?C the equilibrium constant can be expressed in terms of molarity Ke or partial pressure Kp. Which is true about the numerical value of Kp ?
AKc is equal to Kp if the total moles of reactants and products are equal
BKc is generally less than Kp
CKc is generally greaer than Kp
DKc is generally equal to Kp
Correct answer
A. Kc is equal to Kp if the total moles of reactants and products are equal
Explanation
Kc is equal to Kp if the total moles of reactants and products are equal is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
