1.	What happens to the peak of the curve in the Maxwell-Boltzmann distribution graph if temperature increases?(a) Shifts forward and upward(b) Shifts forward and downward(c) Shifts backward and upward(d) Shifts backward and downwardThe question was asked in an online quiz.This question is from Chemical Kinetics in chapter Chemical Kinetics of Chemistry – Class 12
Answer» Right ANSWER is (b) Shifts forward and DOWNWARD To EXPLAIN I would say: With the increase of temperature, the peak shifts forward but downward. This is because with the increase of temperature, the most PROBABLE kinetic energy increases and the FRACTION of molecules possessing most probable kinetic energy decreases.
