For the equilibrium N₂O₄(g) ⇌ 2NO₂(g), the forward reaction is endothermic. Which change will shift the equilibrium to the right?
Increasing the temperature
Decreasing the temperature
Increasing the pressure
Adding a catalyst
📝 Detailed explanation
For an endothermic reaction, heat acts as a reactant. Increasing temperature shifts the equilibrium toward the product side (right) to absorb excess heat.
