← ScienceWhich outcome occurs when thermal energy drives an endothermic molecular reaction past equilibrium?
A)Reactant concentrations decrease initially faster eventually✓
B)Overall system entropy will tend to decrease
C)Activation energy permanently significantly changes
D)Activation energy permanently reduces drastically
💡 Explanation
Driving the reverse reaction faster initially than thermal effects because the equilibrium shifts, creating immediate change via Le Chatelier's principle; therefore, reactant concentrations reduce relatively faster earlier rather than system entropy changing since entropy would consistently increase endothermically.
