Answer:

The activation energy

Explanation:

The activation energy is the energy hump that lies between reactants and products. It is the energy barrier that reactants must cross before they are converted into products.

Based on the collision theory, only particles that possess the activation energy are able to collide in such a way that leads to reaction.

Collision of particles having an energy content less than the activation energy of the reaction merely leads to elastic collision between such particles.

The molarity of a solution prepared by dissolving 4.11 g of NaI in enough water to prepare 312 mL of solution is
Dimas [21]

Answer:

The correct answer is 8.79 × 10⁻² M.

Explanation:

Based on the given information, the mass of NaI given is 4.11 grams. The molecular mass of NaI is 149.89 gram per mole. The moles of NaI can be determined by using the formula,

No. of moles of NaI = Weight of NaI/ Molecular mass

= 4.11 / 149.89

= 0.027420

The vol. of the solution given is 312 ml or 0.312 L

The molarity can be determined by using the formula,

Molarity = No. of moles/ Volume of the solution in L

= 0.027420/0.312

= 0.0879 M or 8.79 × 10⁻² M
