How does the equilibrium position shift if a reactant is added or a product is removed?

Changes in Concentration If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants. Or, if we remove reactants from the system, equilibrium will also be shifted to the left.

What will happen to the amount of product in an endothermic reaction at equilibrium if the temperature is increased?

If the reaction is endothermic as written, an increase in temperature will cause the forward reaction to occur, increasing the amounts of the products and decreasing the amounts of reactants. Lowering the temperature will produce the opposite response.

What would happen if the kinetic energy of the reactants was not enough to provide the needed activation energy?

What would happen if the kinetic energy of the reactants was not enough to provide the needed activation energy? -The products would form at an unstable energy state.

How does the energy of the activated complex compare with the energies of the reactants and products?

How does the energy of the activated complex compare with the energies of reactants and products? It is higher than the energy of both reactants and products. the energy required to form the activated complex.

Why does adding reactants affect equilibrium?

One way is to add or remove a product or a reactant in a chemical reaction at equilibrium. When additional reactant is added, the equilibrium shifts to reduce this stress: it makes more product. When additional product is added, the equilibrium shifts to reactants to reduce the stress.

What causes equilibrium shifts?

If the stress applied to a system in equilibrium is a change in the concentration of a component of the equilibrium, the system shifts to counteract that change. If the concentration of a substance is increased, the reaction that consumes that substance is favored, and the equilibrium shifts away from that substance.

What factors affect endothermic reactions?

Temperature. Increasing the temperature shifts the equilibrium in the direction of the endothermic reaction. This reduces the effects of the change because, during an endothermic reaction, energy is transferred from the surroundings.

What would happen if there were no kinetic energy?

Without kinetic energy, you end up with a completely motionless mass of matter at absolute zero, eternal and unchanging.

Is it possible for the reaction to happen even if reactants did not reach the activation energy?

The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.

What takes place in an activated complex quizlet?

When two reactant particles collide, they may form an activated complex. An activated complex is an unstable arrangement of atoms that forms for a moment at the peak of the activation-energy barrier. The activated complex forms only if the colliding particles have enough energy and if the atoms are oriented properly.

Why do particles need energy when they collide?

In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic energy) to break chemical bonds; this energy is known as the activation energy. As the temperature rises, molecules move faster and collide more vigorously, greatly increasing the likelihood of bond breakage upon collision.
