What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
What has to be strong in order to cause a chemical reaction to take place?
Chemical reactions are driven by the amount of energy used to break the bonds in the reactants ( the activation energy) and the energy released by making new bonds in the products. The stronger the forces holding together the molecules of products, the more readily the reaction takes place. The difference between the energy produced in making the bonds and breaking the bonds is called ENTHALPY. The reaction can also be driven if the products have a greater degree of disorder (ENTROPY) than the reactants.
What describes the potential energy diagram of an exothermic reaction?
The potential energy of the reactants is greater than the potential energy of the products.
Looking at a free energy diagram for an equilibrium reaction what scenarios will favor the formation of more product?
The concentration of reactants is greater than the concentration of reactants at equilibrium. The concentration of products is less than the concentration of products at equilibrium
In chemical equilibrium what happens when Q is greater than K?
If Q > K, the reaction will move towards the reactants If Q < K, the reaction will move towards the products
Why amount of reactant and product do not change in reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
What is relationship between active mass and rate of reaction?
The rate of a chemical reaction increase when the concentration of the reactants increase.
Does the size of the reactants affaect the speed of a chemical reaction?
Yes. The more surface area that is exposed, the greater the speed of the reaction.
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
What if kc expression is greater than 1 in chemistry?

Does an exothermic reaction contain more chemical energy than reactants?
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.

The potential energy of the reactants is greater than the potential energy of the products.
An energy diagram shows the reactants having greater energy than the products illustrates what?
This shows that the reaction is endothermic because energy is absorbed in the reaction and not produced.
What statement describes the potential energy diagram of an endothermic reaction?
The potential energy of the products is greater than the potential energy of the reactants.
