← ScienceWhich outcome occurs when the temperature of a nitrogen fixation process in soil with a molybdenum catalyst decreases significantly?
A)The equilibrium constant decreases sharply.✓
B)The rate constant increases drastically.
C)Activation energy approaches zero Kelvin.
D)The catalyst increases reaction intermediates.
💡 Explanation
A lower temperature slows kinetic activity; it shifts reaction equilibrium due to the van't Hoff equation; the **equilibrium constant diminishes** heavily. Therefore, lower conversion is seen because equilibrium shifts, rather than reduced activation energy, which remains constant, therefore rate constant does not substantially increase .
