The graph shows the amount of a gaseous product formed over time during two trials of a reaction. A different concentration of a reactant was used during each trial while other factors were kept constant. (see graph)

Which of the following statements explains which trial has a higher concentration of the reactant?

Trial 1, because the final amount of product formed is higher.

Trial 1, because this reaction lasted for a longer duration than Trial 2.

Trial 2, because this reaction was initially fast and slowed down later.

Trial 2, because the amount of product formed per unit time is higher.

Trial 2, because the amount of product formed per unit time is higher.

Explanation:

I have the same question

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
