If entropy increases and enthalpy and temperature remain constant, the Gibbs free energy

Chemistry
1 answer:
WARRIOR [948]3 years ago
4 0

Answer:

A. decreases

Explanation:

The equation for the change in free energy is dG = dH - TdS. Where H is the enthalpy, S is the entropy and T is the Kelvin temperature. Since the change in G depends on minus T times the change in S, if the entropy decreases (that means dS is negative) then -TdS is positive. Hence, when the temperature increases the numeric value of the free energy becomes larger.  Just the opposite is true if the entropy increases. In this case dS will be positive and -TdS becomes more negative when the temperature goes up. So the numeric value of the free energy becomes smaller.

oksano4ka [1.4K]

Answer:

The true statement is:

They are formed when atoms of different elements combine.

Explanation:

Compounds are formed when atoms of different elements combine.

Atoms of different elements combine with each other to attain stable electronic configuration.

The atoms can combine with each other in two different ways:

1) By sharing the electrons

2) By exchanging electrons

When they share electrons with each other, they form a covalent bond.

When they exchange electrons, they form an ionic bond.
