← ScienceWhich consequence results when temperature increases while rate constants remain unchanged?
A)Exothermic reaction becomes kinetically controlled
B)Reactions cannot reach thermodynamic equilibrium✓
C)Pre-exponential factor approaches Planck’s constant
D)Reverse reaction occurs extremely rapidly
💡 Explanation
A system cannot approach standard equilibrium because constant Keq is reliant on rate constants but change independently. Temperature increases reactant energy, but if rate constants don't change, equilibrium can't occur; therefore, the system remains unbalanced, rather than shifting as expected for changed temperature conditions.
