What is the best way to reduce the activation energy?
Ksivusya [100]

Answer:

The method of hurrying up a reaction by decreasing its activation energy is called as catalysis, and the circumstance that's added to reduce the activation energy is termed as the catalyst.

Explanation:

Organic catalysts are named as enzymes. Enzymes are protein particles in cells which act as catalysts. Enzymes are proteid particles in groups which act as catalysts. Enzymes rush up biochemical effects in the thing but do not become used up in the method. Nearly all biochemical effects in living things require enzymes. Among an enzyme, biochemical effects go extremely quicker than they would without the enzyme.

If a solution containing A+ ions and a solution containing B- ions have just been mixed and [A+][B-] is greater than Ksp of AB,
frozen [14]

Answer:

Explanation:

In the solution of AB , they are split  to give ions as follows

AB ⇄ A⁺ + B⁻

Product of concentration of A⁺ and B⁻ in saturated solution of AB is constant .

This is called Ksp

Ksp = [A⁺] [ B⁻]

If product of concentration of A⁺  and B⁻ exceeds Ksp , the equilibrium shifts to the left side and excess ions come out of solution in the form of precipitate. So second option is the answer.

What is the relationship between the amount of substance ( concentration) and reaction rates?
jekas [21]

Answer:

Increasing the concentration of the reagents makes the collision between two molecules of the reagents more likely, thereby increasing the probability that the reaction will occur between these reagents.

As for the relationship between concentration and volume, density also comes into play, a higher volume, lower molarity and also lower concentration.

The pressure when increasing could generate a closer approach between the particles, therefore generating an increase in the reaction speed.

Pressure and volume are related but inversely proportional, therefore if the volume increases the pressure decreases and so on.

the reaction rate increases as the contact surface area increases. This is due to the fact that more solid particles are exposed and can be reached by reactant molecules.

A perfect reaction where the collision is promoted and the reaction speed advances is with the presence of a solvent, with an increase in pressure and a decrease in volume, with an increase in the exposure of the surface, with the presence of a catalyst, with increasing temperature and with increasing entrance

Explanation:

The reaction rate is defined as the amount of substance that is transformed into a certain reaction per unit of volume and time. For example, the oxidation of iron under atmospheric conditions is a slow reaction that can take many years but over time it is oxidized sooner or later by the oxygenation of its surface layer, but the combustion of butane in a fire is a reaction that happens in fractions of seconds, giving rise to an exothermic reaction with products such as CO2 and H2O
