Answer:
<u>Option B is correct</u>
Explanation:
Step 1: Define volatility
In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.
At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly , while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.
The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,
Step 2: In this case:
⇒ O<u>ption A is false</u> because the pressure will be higher when volatility is higher.
<u>⇒ Option B is correct</u> because higher volatility means evaporating more quickly
<u>⇒ Option C is false</u> because higher volatility means higher pressure. When pressure increases, the surface tension decreases.
<u>⇒ Option D is false</u> because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
Answer: "The reactants are higher in energy than the products"
Explanation:
The exothermic reactions are characterized by the release of heat to the surroundings. The reactants lose heat that is delivered to the surroundings which implies that the products will be lower in energy than the reactants.
The hills that you can see in a reaction energy diagram are not related with the final change of energy. The hills are an indication of the activation energy needed to start the reaction, but they do not measure the change of energy from the products to the reactants.
The enthalpy that is a state variable that identifies the content of heat. Then the change of enthalpy for the exothermic reactions is negative, meaning that the energy of the products is lower than the energy of the reactants.
