Question

First, launch the video below. During the video, you will be asked a conceptual question about tile key concept Alter watching the video, answer the related question at the right You can watch the video again at any point to review Consider the energy diagram for a general reaction, reactants > products What are the expected signs of Delta E_xyx, is positive and Delta E_ ? Delta E_xyx, is positive and Delta E_ is positive Delta E_xyx, is negative and Delta E_ is positive Delta E_xyx, is positive and Delta E_ is negative Delta E_xyx, is negative and Delta E_ is negative

Explanation / Answer

During reaction internal energy of a reactant increases taken energy (basorbed) a positive change increases.

internal energy of a product decreases i.e. released a negative change will occur.

delta E system is positive & delta E surrounding is negative,
