when a reaction is exothermic, a decrease in temp. will favor the reaction and more product will be formed and the reactant will decrease...and as Kc= [conc. of products]/[conc. of reactants]. So as the conc. of product is more than the reactant..kc will be a bigger no..hence Kc will be more.

When circumstances change, the equilibrium will shift to oppose the change.
If the temperature decreases, the equilibrium will shift in such a way that more heat is produced. In an exothermic reaction, it will favor the products and shift to the right, increasing the Kc.

BY lowering the temperature the Kc will increase. Because the reaction goes ahead.

All I know is if a reaction is exothermic(exit) then temperature is leaving the system to the surrounding. Therefore, the tempature of the system is decreasing and the temperature of the surroundings is increasing.

a million. verify out an exothermic rx as A + B ---> C + D + warmth in case you do away with warmth, i.e. decrease temp, the rx will make greater products. A 2. The expression for ok for rx A + B <---> C + D is high-quality = [C][D]/[A][B] If ok
