| 21. | The equilibrium is characterized by, which is exothermic.
|
| 22. | An exothermic reaction is not a chemical or physical reaction that releases heat.
|
| 23. | This is the well known exothermic reaction which takes place in charcoal burning.
|
| 24. | The negative value means that heat is produced and the system is exothermic.
|
| 25. | Since these reactions are exothermic, they always become feasible at lower temperatures.
|
| 26. | A reaction which is endothermic at one temperature can be exothermic at another.
|
| 27. | The reaction is so exothermic that ignition is possible.
|
| 28. | During the exothermic free-radical polymerization process, the cement heats up.
|
| 29. | Take an exothermic reaction, such as regular combustion.
|
| 30. | The absorption reaction is a gas liquid reaction, strongly exothermic, here:
