Consider the following equilibrium between N2O4 and NO2.[Heat is added to a brown 2 NO2 gas to yield a colorless N2O4 gas]Which
LekaFEV [45]

Answer:

a.Low temperature

Explanation

Equation of reaction:

2NO2 <==> N2O4(g) ∆H = +ve

To cause the reaction to become darker brown means to produce more of NO2 gas. That is backward reaction.

Since the reaction is endothermic, decrease in temperature will shift the equilibrium position to the left thereby favouring backward reaction. This is in line with Me Chatelier's principle.

High pressure will rather favour forward reaction (it is not the right option).

In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater t
Vinil7 [7]

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.
