The main difference between HCV and LCV is that in HCV, byproducts of the reaction are allowed to cool down to the room temperature whereas, in LCV, byproducts are allowed to escape. Therefore, some amount of heat which is going to be lost with the byproducts can be recovered in HCV while a specific amount of heat is carried away by …
