← ScienceWhich consequence results when the activation energy changes to increase the reverse rate constant?
A)Equilibrium shifts toward products
B)Equilibrium constant decreases✓
C)Forward rate becomes limited
D)Reactant concentration remains constant
💡 Explanation
A higher reverse rate constant, due to a lower activation energy for the reverse reaction, decreases the equilibrium constant because the equilibrium constant is the ratio of forward to reverse rate constants; therefore, the equilibrium shifts toward reactants, rather than products under such conditions.
