The slow rate of a particular chemical reaction might be attributed to which of the following?


a) a low activation energy b) a high activation energy
c) high temperature

Respuesta :

The slow rate of a particular chemical reaction might be attributed to a) a low activation energy

Explanation:

Slow rate of reaction happens when the particles that are present in the elements that are to react do not interact fast enough or there is a chemical need of a catalyst.

When the activation energy is high the reaction takes place is less time than when the activation energy is actually low.

According to the theory of kinetics if the reaction is to be heated, the activation energy can be pumped up and the reaction will take place sooner.

The slow rate of a particular chemical reaction might be attributed to b) a high activation energy.

What is the rate of reaction?

The rate of reaction is the speed at which a chemical reaction takes place.

The rate of reaction (r) is proportional to the rate constant (k).

The rate constant depends on the temperature (T) and the activation energy (Ea), as stated in the Arrhenius equation.

[tex]k = A.e^{-Ea/R.T} [/tex]

where,

  • A is the collision factor.
  • R is the ideal gas constant

The slow rate of a particular chemical reaction might be attributed to which of the following?

  • a) a low activation energy. No, since a low Ea, implies a high k and thus a high r.
  • b) a high activation energy. Yes.
  • c) high temperature. No, since a high T, implies a high k and thus a high r.

The slow rate of a particular chemical reaction might be attributed to b) a high activation energy.
