Answer:
a) the reverse reaction is favoured
b) the forward reaction is favoured
c) the forward reaction is favoured
Explanation:
The equation ought to have been correctly written as;
3A + 2B --------> C + 2D. ∆H =20 kJ
Actually, we can see that the reaction is endothermic since ∆H= positive.
We know that when pressure is decreased, the reaction tends towards the side with higher total volumes. There are five volumes(moles) of reactants and three volumes(moles) of products. A decrease in pressure will favour the reverse reaction.
Being an endothermic reaction, increase in temperature is known to favour the forward reaction. Similarly, removing D will drive the equilibrium forward thereby favouring the forward reaction.
Answer:
the heat source must be greater than 100°C
the water must be permitted to evaporate quickly
the system must be sealed and become pressurized above atmospheric pressure
the vapor pressure must be kept below 760 mmHg
Explanation:
A superheated water is a dry form of steam in which hydrogen bonds that strongly binds the molecules of water has been overcome.
Superheated water finds application in a wide range of places. For example they are used for sterilization of clinical equipment.
- To produce steam or superheated water, the temperature of the source must be greater than the boiling temperature and less than the critical temperature at 374°C.
- Since superheated water is steam and steam is water in gaseous form. The water must be made to evaporate more quickly than it should condense back.
- High pressure and sealing the system helps to produce superheated water very fast.
- If the pressure between the vapor is kept low, water will boil faster.
Reduction I think... not entirely sure though... when a molecule loses oxygen...?
Answer: ( Outwash )
hope this helps!
Answer:
I would say you would check for temperature change. A chemical reaction is shown by a change in color, a change in temperature, solids forming, odor, or smoke. So check temperature.
edit: while odor is an option in the answer. i think temp is a better choice.
