How can the effect of heat on a reaction be determined?
A. Heat always shifts a reaction toward reactant formation.
B. Heat is treated as a reactant or a product.
C. Heat will increase reaction rate, but not equilibrium position.
D. Heat always shifts a reaction toward product formation.
Answer (2)
The effect of heat on a reaction can be determined using Le Chatelier's principle, which states that heat can act as either a reactant or a product depending on the type of reaction. In exothermic reactions, heat shifts the equilibrium toward reactants, while in endothermic reactions, it shifts toward products. Therefore, the correct answer is B: heat is treated as a reactant or a product.

Heat affects chemical reactions by shifting equilibrium positions according to Le Chatelier's principle. In exothermic reactions, excess heat shifts toward reactants, while in endothermic reactions, it shifts toward products. Thus, heat can be viewed as a reactant or product depending on the type of reaction. ;
