Question

Choose the correct answers from the alternatives given .
Which of the following statements is not a consequence of the second law of thermodynamics?

• A. While the total amount of energy is unchanged, the energy lost as heat is no longer useful to the cell in doing work
• B. Reactions that occur spontaneously are those that increase the amount of useful energy in a system
• C. Amount of disorder in the universe is always increasing
• D. To maintain rganisation of a cell, a continual input of energy is required

Answer 1

The correct option is B Reactions that occur spontaneously are those that increase the amount of useful energy in a system

In spontaneous reactions release free energy and it moves to a lower, more thermodynamically stable energy state. Hence, instead of an increase in the amount of useful energy in a system spontaneous reactions release free energy.

So, the correct option is 'Reactions that occur spontaneously are those that increase the amount of useful energy in a system'.
