What is equilibrium constant?

Equilibrium constant is defined as the product of concentration of products at equilibrium by the product of concentration of reactants at equilibrium. This representation is known as equilibrium law or chemical equilibrium. The thermodynamically correct equilibrium constant expression relates the activities of all of the species present in the reaction.

How to Calculate Equilibrium Constant at Equilibrium?

Equilibrium Constant at Equilibrium calculator uses Equilibrium Constant = 10^((-Change in Enthalpy+(Change in Entropy*Temperature))/(2.303*[R]*Temperature)) to calculate the Equilibrium Constant, The Equilibrium constant at equilibrium formula is defined as 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. Equilibrium Constant is denoted by K_c symbol.

How to calculate Equilibrium Constant at Equilibrium using this online calculator? To use this online calculator for Equilibrium Constant at Equilibrium, enter Change in Enthalpy (ΔH), Change in Entropy (ΔS) & Temperature (T) and hit the calculate button. Here is how the Equilibrium Constant at Equilibrium calculation can be explained with given input values -> 235824.9 = 10^((-190+(220*85))/(2.303*[R]*85)).

FAQ

What is Equilibrium Constant at Equilibrium?

The Equilibrium constant at equilibrium formula is defined as 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 and is represented as K_c = 10^((-ΔH+(ΔS*T))/(2.303*[R]*T)) or Equilibrium Constant = 10^((-Change in Enthalpy+(Change in Entropy*Temperature))/(2.303*[R]*Temperature)). Change in enthalpy is the thermodynamic quantity equivalent to the total difference between the heat content of a system, Change in entropy is the thermodynamic quantity equivalent to the total difference between the entropy of a system & Temperature is the degree or intensity of heat present in a substance or object.
