Question

1. what is the significance of the maxwell - boltzmann distribution in understanding chemical reactions? a) it describes the conservation of mass in reactions b) it depicts the distribution of molecular speeds c) it predicts the exact outcome of chemical reactions d) it calculates the exact energy of molecules why did you pick your response? 7) according to the passage, the second law of thermodynamics affects chemical reactions by: a) decreasing entropy to zero b) ensuring reactions do not occur c) influencing the directionality and spontaneity of reactions d) eliminating the need for activation energy why did you pick your response? 8) how does quantum mechanics contribute to our understanding of chemical reactions? a) it negates all the laws of classical physics b) it explains behaviors of electrons that classical physics cannot c) it proves that chemical reactions are random d) it defines the exact temperature for all reactions why did you pick your response?

Explanation:

Question 6:

The Maxwell - Boltzmann distribution shows how molecular speeds are distributed in a gas at a given temperature. It is not about mass conservation, predicting exact reaction outcomes, or calculating exact molecular energy.

Question 7:

The second law of thermodynamics deals with entropy and determines the direction and spontaneity of chemical reactions. Entropy never decreases to zero in real - world reactions, reactions do occur, and it doesn't eliminate the need for activation energy.

Question 8:

Quantum mechanics helps explain electron behavior in atoms and molecules, which classical physics cannot fully account for. It doesn't negate all classical physics laws, prove reactions are random, or define exact reaction temperatures.

Answer:

Question 6:

B. It depicts the distribution of molecular speeds

Question 7:

C. Influencing the directionality and spontaneity of reactions

Question 8:

B. It explains behaviors of electrons that classical physics cannot
