Question

Consider the following chemical reaction: Select all the statements that are correct: The reactants can adopt a fewer number of configurations than the products The reaction should become more product favored at low temperatures The reactants can adopt a larger number of configurations than the products The potential energy of the reactants is lower than the potential energy of the products The potential energy of the reactants is higher than the potential energy of the products The reaction should become more product favored at high temperatures

Explanation / Answer

correct statements-

The potential energy of the reactants is higher than the potential energy of the products

The reaction should become more product favore at low temperatures.

The reactant can adopt a larger number of configurations than the products

reason =

The potential energy stored by the reactant in the form of bond energies of the reacting molecules is higher as they are all gaseous atoms.The product has liquid molecules that are formed by the release of energy(cooling) ,so has lesser potential energy.

At low temperatures , the mobility of gaseous atoms is low , so low kinetic energy leads to high pressure conditions and hence more interaction between slow gaseous atoms(needed to combine to form products with less kinetic energy)

The entropy is the measure of freely moving particles,which is higher in reactants as there are more gaseous particles.So its configuration for reaction is higher.
