Assertion: The activity coefficients of the components in an ideal solution are equal to 1.
Reasoning: In an ideal solution, the interactions between the two components are the same as the interactions between like molecules.
Both assertion and reasoning are true and the reasoning is the correct explanation of the assertion.
Both assertion and reasoning are true but the reasoning is not the correct explanation of the assertion.
Assertion is true but the reasoning is false.
Assertion is false but the reasoning is true.
In an ideal solution, the interactions between the two components are the same as the interactions between like molecules. Therefore, the activity coefficients of the components in an ideal solution are equal to 1. This is because the activity of a component is defined as the product of the mole fraction and the activity coefficient of that component. In an ideal solution, the activity coefficient is equal to 1, which means that the activity of the component is equal to its mole fraction.
