Exothermic reaction

Postby Ghadir Seder 1G » Sun Jan 26, 2020 1:00 pm

when a reaction is exothermic, how does increasing or decreasing the temperature affect the reaction?

When a reaction is exothermic the heat can be considered to be a product, so if the temp increases then the reaction will shift toward the reactants and if the temp decreases then the reaction will shift toward the products. Hope this helps.

If a reaction is exothermic, an increase in its temperature will cause the reaction to shift to the left and a decrease in its temperature will cause the reaction to shift to the right!

in an exothermic reaction if temp is decreased the rxn will move forward as it is a "product" (is released)

if the reaction is exothermic, then decreasing the temp will shift it to products.

Increasing the temperature will shift the reaction to the left and decreasing it will shift it to the right. This has to do with the fact that exothermic reactions have heat as a product

Exothermic reaction: - increasing the temp will favor formation of reactants
- decreasing the temp will favor formation of products

In an exothermic reaction, decreasing the temperature will favor the formation of products, while increasing temperature would favor formation of reactants.

If the reaction is exothermic, increase in temperature would cause the reaction to shift left and decrease in temperature would cause the reaction to shift right

In an exothermic reaction, because the heat is technically treated as a "product", increasing the temperature would cause the reaction to shift towards the left.

In an exothermic reaction when temp is increased, the reaction shifts towards the reactants, and when temp is decreased, the reaction shifts towards the products.

For reactions that are exothermic, a shift to the left means we are increasing the temperature and a shift to the right means we are decreasing the temperature

if temp increases then the reaction will shift to the left, if temp decreases then the reaction will shift to the right

A reaction is exothermic when it releases heat. Exothermic reactions have a negative (DELTA H) value. When exothermic reactions are heated they will favor the production of the reactants. Another way to phrase this is that when an exothermic reaction is heated the reaction will move in the reverse direction. Temperature is the only quality that affects the K constant value. In an exothermic reaction, a temperature increase will cause K to decrease.

An exothermic reaction means that the reaction is releasing heat to the surroundings. As a result of the increase in heat, the temperature of the rxn also increases. For an endothermic reaction, the reaction absorbs heat, so the temperature decreases.

Since heat is released in exothermic reactions this means that heat could be considered a product. Increasing the temperature would then be increasing the amount of product, causing a leftward shift to reestablish equilibrium. If temperature is decreased then the forward reaction would occur to reestablish equilibrium.

When a reaction is exothermic, increasing temperature would cause the reaction to shift towards the reactants while decreasing temperature would cause the reaction to shift towards the products.

In an exothermic reaction, since heat is being released as a result of the reactants, increasing the temperature would shift towards those reactants. Vice versa for the products: decreasing temperature would shift towards the products.

If a reaction is exothermic, you can treat heat as a "reactant," where increasing the overall temperature will shift the equilibrium to the left, and decreasing the overall temperature will shift the reaction to the right.
