Introduction: Thermodynamics is the study of energy and its transformations that drives all activities of the universe. The system that does not exchange energy with its surroundings is known as a closed system. The system that exchanges energy with its surroundings is known as an open system. There are two laws of thermodynamics, namely: the first law and the second law.

- Which of the following is/are true concerning the first law of thermodynamics? A) Energy cannot be created or destroyed. B) The total amount of energy in the universe is constant. C) Energy can be converted from one form to another. D) It is sometimes referred to as the law of conservation of energy. E) All of the above are true.arrow_forwardWhat are the Determinants of Reaction Rates?arrow_forwardLiving organisms increase in complexity as they grow, resulting in a decrease in the entropy of an organism. How does this relate to the second law of thermodynamics?arrow_forward
- Explain the first law of thermodynamics and give examplesarrow_forwardWhat is the net change in energy in the reaction shown (decrease, increase, or little change in energy) ? Is it spontaneous?arrow_forwardWhat is the most common form of kinetic energy that is released from chemical energy in chemical reactions?arrow_forward
- Of the three thermodynamic quantities, enthalpy, free energy, and entropy, which provides the most useful indicator of spontaneity in a reaction? Explain.arrow_forwardWhy the endergonic reactions are thermodynamically unfavorable?arrow_forwardWhich of the following statements is true concerning thermodynamics of reactions within a cell? a) Spontaneous reactions always consume energy b) Unfavorable reactions can be coupled to nonspontaneous reactions c) Compartmentalization can be used to drive up the concentration of substrates to force a reaction to occur d) All important reactions are spontaneousarrow_forward
- What is the difference between exothermic and exergonic reactions?arrow_forwardLife is sometimes described as a constant struggle against the second law of thermodynamics. How do organisms succeed in this struggle?arrow_forwardThe first and second laws of thermodynamics are useful for biochemists who investigate chemical reactions in living organisms. Explain why the third law is not useful.arrow_forward
