The value of keq is dependent on temperature

WebSep 6, 2024 · What is KEQ equal to? (1) The equilibrium constant for a reversible chemical reaction. (2) The ratio depicting the concentrations when chemical equilibrium is reached, and expresses the extent to which equilibrium has favoured in either direction. The equilibrium constant is represented by Keq in an equation. WebJan 15, 2024 · The value of K p is independent of pressure, although the composition of a system at equilibrium may be very much dependent on pressure. Temperature …

WebSep 8, 2024 · The value of K (the equilibrium constant) for reaction depends only on temperature and is independent of the pressure or concentrations of reactants/products, presence of catalyst etc. Does K increase with temperature? Because the K value decreases with an increase in temperature, the reaction is an exothermic reaction. WebKeq is the value of Q when the reaction reaches equilibrium. For gases, partial pressures can be substituted for molar concentrations. (Do you see why?)
