Question

Statement 1: An exothermic reaction has a negative value of $△H$.
Statement 2 : In an exothermic reaction the products have less potential energy than the reactants.

• A. Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.
• B. Both Statement 1 and Statement 2 are correct and Statement 2 is not the correct explanation of Statement 1.
• C. Statement 1 is correct but Statement 2 is not correct.
• D. Statement 1 is not correct but Statement 2 is correct.
  
• E. Both the Statement 1 and Statement 2 are not correct.

Answer 1

The correct option is A

Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.

In an exothermic reaction, the products have less potential energy than the reactants thus some energy is released after reaction, making $△H$= negative.
