← ScienceWhich effect arises from running an endothermic chemical reaction to cool a refrigeration cycle?
A)Decrease in power supply needed
B)Increased cycle completion efficiency
C)Lower overall coefficient of performance✓
D)Higher cycle material stress limits
💡 Explanation
Running an endothermic reaction requires additional energy input, leading to an increased overall energy input during the refrigeration cycle, because of increased total energy required and the lower heat removal. Therefore, the coefficient of performance decreases overall, rather than a higher efficiency arising.
