Answer : The correct option is, (B) bimolecular

Explanation :

Molecularity : It is defined as the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.

The given balanced chemical reaction is,

$NH_2Cl(aq)+OH^-(aq)\rightarrow NHCl^-(aq)+H_2O(l)$

The number of reactants molecules taking part in the balanced equation of a reaction are, $NH_2Cl$ and $OH^-$ .

In this reaction, 1 $NH_2Cl$ molecules reacts with the 1 $OH^-$ molecule.

Total number of reactant molecule = 1 + 1 = 2

The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.

Hence, the correct option is, (B) bimolecular

Which reactants would lead to a spontaneous reaction?

sleet_krkn [62]

The reactants that would lead to a spontaneous reaction are Mn2+ and Al3+. Al and Mn are not because they are stable reactants. Mn and Al3+ are not because Mn is stable. Mn2+ and Al are not because Al is stable.

Answer each of the following questions with increases, decreases, or does not change.

Nitella [24]

Answer:

a) increases

b) decreases

c) does not change

d) increases

Explanation:

The vapour pressure of a liquid is dependent on;

I) the magnitude of intermolecular forces

II) the temperature of the liquid

Hence, when any of these increases, the vapour pressure increases likewise.

Similarly, the boiling point of a liquid depends on the magnitude of intermolecular forces present because as intermolecular forces increases, more energy is required to break intermolecular bonds.

Lastly, increase in surface area of a liquid does not really affect it's vapour pressure.
