← ScienceWhich outcome occurs when increasing reactant concentration in equilibrium?
A)Forward reaction rate temporarily increases✓
B)Reverse reaction rate remains constant
C)Equilibrium constant value decreases
D)Product concentration always decreases
💡 Explanation
Increased reactant concentration causes collision frequency and therefore forward reaction rate boosts because more reactant molecules are available; reaction shifts forward to restore equilibrium, rather than staying unchanged unless perturbed with product concentration.
