Units Of Equilibrium Constant
K eq mol l 1 δn. K p bar c d bar a b.
Part 24 What Are The Units For Equilibrium Constant A Ms S B
Dimensionless if the total number of moles of products is equal to the total number of moles of reactants.
Units of equilibrium constant. In this online lecture sibghat ullah explains 10th class chemistry chapter 9 chemical equilibrium the topic being discussed is topic 9 3 equilibrium constant its units. Equilibrium constant k will be given as. This page explains what is meant by an equilibrium constant introducing equilibrium constants expressed in terms of concentrations k c it assumes that you are familiar with the concept of a dynamic equilibrium and know what is meant by the terms homogeneous and heterogeneous as applied to chemical reactions.
K eq mol l 1 c d mol l 1 a b. K eq mol l 1 c d a b. How to calculate k and how to use k to determine if a reaction strongly favors products or reactants at equilibrium.
Although the calculation is usually written for two reactants and two products it works for any numbers of participants in the reaction. Number of moles of products number of moles of reactants k eq or k p will have no units. Punjab text book board.
K p atm or bar c d a b. K nh 3 2 n 2 h 2 3. Kp atm δn or bar δn if δn 0 i e.
The units of k will be k mol litre 1 2 mol litre 1 mol litre 1 3 l 2 mol 2. Equilibrium constant kp equilibrium constant problems equilibrium constant and temperature equilibrium constant expression equilibrium constant and its units 10th. Reversible reactions equilibrium and the equilibrium constant k.
K p atm c d atm a b. The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change for a given set of reaction conditions the equilibrium constant is independent of the initial analytical concentrations of the. 1 h 2 g i 2.
The equilibrium constant k expresses the relationship between products and reactants of a reaction at equilibrium with respect to a specific unit this article explains how to write equilibrium constant expressions and introduces the calculations involved with both the concentration and the partial pressure equilibrium constant. Hence it is concluded that equilibrium constant k has no units i e. Units of equilibrium constant.
The equilibrium constant is a dimensionless quantity has no units.
