When the coke bed has cooled to a temperature at which the endothermic reaction can no longer proceed, the steam is then replaced by a blast of air.
32.
A reaction is said to be exothermic if the reaction releases heat to the surroundings; in the case of endothermic reactions, the reaction absorbs heat from the surroundings.
33.
This is accomplished by firing a chemical projectile into the forehead of the zombie that causes an endothermic reaction that freezes the zombie's brain and temporarily immobilizes it.
34.
In exothermic reactions, increase in temperature decreases the equilibrium constant, " K ", whereas, in endothermic reactions, increase in temperature increases the K value.
35.
In the endothermic reaction N 2 O 4 ( g ) & # 8652; 2NO 2 ( g ), the equilibrium position can be shifted by changing the temperature.
36.
It is the source of heat for powering the endothermic reaction, and it removes coke that tends to form on the iron oxide catalyst through the water gas shift reaction.
37.
These phenomena are due to exothermic or endothermic reactions occurring faster than heat transfer, causing the reacting molecules to have non-thermal energy distributions ( non-Boltzmann distribution ).
38.
Due to various exothermic and endothermic reactions, the blanket may have a power gain factor a few percent higher or lower than 100 %, but that will be neglected here.
39.
An endothermic reaction like your " cold fire " is not self sustaining and won't have the power to suck in light, something that only black holes can do.
40.
Since the exothermic reaction happens at about 650 �C and the endothermic reaction at 850-950 �C, the heat from the carbonator cannot be directly used to heat the calciner.
