Answer: The products will predominate once it reaches equilibrium
Step-by-step explanation:
ΔH refers to the change in enthalpy in a system. It allows to to understand whether heat was absorbed or given away during a process.
Usually when ΔH > 0, the reaction in endothermic, meaning heat was absorbed. When heat is absorbed, equilibrium shifts towards the right side of the chemical equation, where the reactants are written.
When ΔH < 0, like this problem where ΔH = -30 kj, the reaction is exothermic and heat is given off during the process. In order to balance the reaction, equilibrium will shift to the left, towards the products.
