So, the enthalpy change for the production of 0.05 moles of NaCl in the above reaction would be: -2717 J for each 0.05 moles NaCl, or -2717 J/.05 moles = 54,340 J/mole = 54.34 kJ/mole Summary of the terms and symbols Quantity Symbol Unit Meaning Energy transfer that produces or heat J results from a difference in q temperature Measure of the kinetic energy of temperature or K T oC molecular motiom temperature Difference between the final and or K ΔT oC change initial temperatures for a process mass g Amount of material present m Heat required to change the J or J oC-1 heat capacity temperature of a substance one C K-1 degree Heat required to change the J g-1 oC-1 specific heat temperature of one gram of a s or J K-1 capacity substance one degree
