It is the balance between thermal energy and intermolecular forces that determines the state of matter of any substance at room
ExtremeBDS [4]

Answer:

The correct option is;

2) Thermal energy increases by a factor of R

Explanation:

The equipartition energy theorem states that when molecules are in a state of thermal equilibrium, particles within the system posses equal average energy with each degree of freedom which can be known as energy due to a state of having a particular temperature or thermal energy given by the relation

E_{th} = Kinetic energy of translation + Kinetic energy of rotation + Energy of vibration

For a mono-atomic gas, E_{th} = 3/2·n·R·T

For a diatomic gas, E_{th} = 5/2·n·R·T

For a solid element, E_{th} = 3·n·R·T

Therefore, as the temperature is doubled, the thermal energy increases by a factor of R.

Which is not true regarding reaction rates? (2 points)
PtichkaEL [24]

Let us consider each statement one by one

a) Catalysts are the substance which alter the reaction pathway where activation energy of reaction is less that the un catalyzed reaction. They are not used up in the reaction . the catalyst is restored in the reaction.

b) As mentioned above, the catalyst speed up reaction by lowering the activation energy

c) During a reaction the reactants are consumed up and products are formed. so there is a decrease in concentration of reactant.

Thus all the above statements are true.

D) the rate of decrease in concentration of reactants depends upon the coefficient of reactant in balanced chemical reaction.

For example

H_{2} (g)  + \frac{1}{2} O_{2} (g) -->    H_{2}O(g)

Here the rate of decrease in concentration of hydrogen will be double the rate of decrease in concentration of oxygen.

Homogeneous mixtures have components that are unevenly spaced throughout true or false
givi [52]

Answer:

False

Explanation:

Mixtures are impure substances.

There are two types of mixtures based on the number of coexisting phases.

Homogeneous mixtures have their constituents existing in one single phase. The components are evenly spaced.

Heterogeneous mixtures have their constituents existing in at least two different phases. Therefore, they are unevenly spaced due to the phases present within the mixture.
