WebAnswer = make it smaller. To see this, write the K eq expression for the reation: K eq = [HCl] 2 / ([H 2] [Cl 2]) As the equilibrium shifts to the left, the [HCl] goes down and both the [H 2] and [Cl 2] increase. This makes the numerator smaller and the denominator larger. The K eq decreases in value and heat is added to an exothermic reaction. WebDifferent units of temperature are Celsius (˚C), Kelvin (K), and Fahrenheit (˚F). It is a factor which has varying impacts on different processes and physical properties. One of the … WebSep 4, 2024 · Does increasing temperature increase or decrease KEQ? Since reactants are in the denominator of the K expression, increasing temperature will cause K to decrease. The opposite is true for exothermic reactions, in which an increase in temperature will cause K to increase. Hope this helps! gran smartphone
