SUMMARY

The discussion clarifies the concept of molar enthalpy change, emphasizing that it is calculated by dividing the total enthalpy change (in kJ) by the number of moles of the substance involved. Molar enthalpy change is expressed in units of kJ/mol. Participants confirmed that molar enthalpy change relates specifically to the moles of solutions used, not their concentration. The formula provided, "Molar enthalpy change = (enthalpy change/no. of moles)," is definitive for calculating this value.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with enthalpy concepts
  • Knowledge of mole calculations
  • Basic proficiency in chemistry
NEXT STEPS
  • Research the concept of enthalpy in thermodynamics
  • Learn about calculating enthalpy changes for chemical reactions
  • Explore the relationship between moles and molarity in solutions
  • Study the implications of molar enthalpy change in calorimetry
USEFUL FOR

Chemistry students, educators, and professionals involved in thermodynamics and calorimetry who seek to deepen their understanding of enthalpy changes and their calculations.

What is the difference between enthalpy change in kj and molar enthalpy change?



Is molar relating to the concentration of solutions used or the moles of solutions used?



Do you work out the enthalpy change and divide by the amount of moles to get kj per mol?


CAN ANYONE HELP ME!

Molar enthalpy change = (enthalpy change/no.of moles)
So, its units are kJ/mol
