Q
Q: In a chemical reaction, if ΔH is negative, the reaction is classified as:
Solution:
A negative ΔH indicates that the reaction releases heat, classifying it as exothermic.
Steps: 4
Show Steps
Step 1: Understand what ΔH means. ΔH represents the change in enthalpy, which is a measure of heat content in a chemical reaction.
Step 2: Identify the sign of ΔH. If ΔH is negative, it means that the reaction is losing heat.
Step 3: Recognize what it means to lose heat in a reaction. When a reaction loses heat, it means that it is releasing energy into the surroundings.
Step 4: Classify the reaction based on the heat change. A reaction that releases heat is called an exothermic reaction.
