← ScienceWhich consequence appears when injecting excess product into equilibrium?
A)Reactant concentration will exponentially decrease
B)Temperature immediately becomes proportionally cooler
C)Reverse reaction rate temporarily exceeds forward✓
D)Catalyst deactivation rate sharply accelerates
💡 Explanation
Adding product forces the equilibrium to shift left; Le Chatelier's principle explains this. The system favors reactants to offset increased product, because the **change in equilibrium** causes the reverse reaction rate to surge temporarily, rather than catalyst deactivation alone.
