chapter 1-3 chemistry

The entropy of a substance increases as it transitions from solid, liquid to gas.

• True

• False

Entropy is not a measure of energy itself but of how energy is distributed within the system

• True

• False

An increase in system’s enthalpy leads to an increase in entropy

• true

• false

Most of the reactions are spontaneous by nature as it adds up entropy in the universe.

• true

• false

Whenever the volume is doubled, the system will always favor the side of the reaction that produces lesser to greater number of moles of substances

• true

• false

A system is said to reach equilibrium when the concentration of the reactants is equal to the concentration of the products.

• true

• false

A negative value of Gibbs free energy (G) indicates that the chemical process is nonspontaneous

• true

• false

Hydronium ion is an example of amphoteric substance that can act as either acid or base during neutralization process.

• true

• false

Arrhenius defined bases as substances that accepts hydrogen ions when dissolved in water.

• true

• false

Any chemical reaction that produces more gas molecules results in an increase in entropy.

• true

• false
