Question

100 Points!!!!!!

The effect of temperature on equilibrium has to do with the heat of reaction. If the reaction being considered has a ΔH of 57 kJ, how can you change the temperature to increase the product? Remember that for an endothermic reaction, heat is absorbed in the reaction, and the value of ΔH is positive.

A If we raise the temperature, the equilibrium will shift to the left, creating more product.If we raise the temperature, the equilibrium will shift to the left, creating more product.
B If we raise the temperature, the equilibrium will shift to the right, creating more product.If we raise the temperature, the equilibrium will shift to the right, creating more product.
C If we lower the temperature, the equilibrium will shift to the right, creating more product.If we lower the temperature, the equilibrium will shift to the right, creating more product.
D If we lower the temperature, the equilibrium will shift to the left, creating more product.

Answer 1

Option B: If we raise the temperature, the equilibrium will shift to the right, creating more product.

For an endothermic reaction with a positive Delta H, increasing the temperature leads to a shift in equilibrium to the right, thus forming more products. Therefore correct answer is Option B.

Step-by-step explanation:

When examining the effect of temperature on equilibrium, it is essential to understand whether a reaction is endothermic or exothermic.

Since the reaction in question has a positive ΔH of 57 kJ, it is an endothermic reaction, meaning heat is absorbed as it proceeds.

In the case of an endothermic reaction, if you increase the temperature, you are effectively adding heat to the system, which can be considered as adding a reactant in the reaction equation:

energy + reactants → products

According to Le Chatelier's principle, the system will shift to relieve the stress of this additional energy, thus favoring the formation of more products.

Therefore, raising the temperature causes the equilibrium to shift to the right, resulting in more product formation.
