3 cards from this section. Quick, good the night before a test.
What is the definition of an endothermic reaction?
Think about heat transfer in relation to the surroundings.
Name an example of an endothermic reaction.
Consider processes where heat is absorbed.
What happens during an endothermic reaction?
Think about energy flow in the reaction.
ΔH for an endothermic reaction is:
Recall how ΔH is defined for different types of reactions.
Calculate the enthalpy change (ΔH) for an endothermic reaction where 250 grams of ice melts at 0 °C to become liquid water at 0 °C. Given that the enthalpy of fusion for ice is 334 kJ/kg.
Convert grams to kilograms and use the given enthalpy of fusion value.
Discuss how temperature changes during an endothermic reaction can affect the surrounding environment, giving an example.
Consider the applications of these reactions in practical scenarios.
