Question: Which of the following conditions will favor the spontaneity of a reaction?

Options:

Correct Answer: Low ΔH and high ΔS

Solution:

A reaction is favored when it has low ΔH (exothermic) and high ΔS (increased disorder).

Which of the following conditions will favor the spontaneity of a reaction?

Which of the following conditions will favor the spontaneity of a reaction?

Step 1: Understand that a reaction's spontaneity is about whether it can happen on its own without outside help.
Step 2: Learn that ΔH (change in enthalpy) tells us if a reaction releases or absorbs heat.
Step 3: Know that a low ΔH means the reaction is exothermic, which is favorable for spontaneity.
Step 4: Understand that ΔS (change in entropy) measures the disorder or randomness in a system.
Step 5: Realize that a high ΔS means more disorder, which is also favorable for spontaneity.
Step 6: Conclude that a reaction is favored when it has both low ΔH (exothermic) and high ΔS (increased disorder).
