Why is the Harbor process run at 200atm?

The Harbor process is run at 200 atm to promote the synthesis of methanol from carbon monoxide and hydrogen. The high pressure helps overcome the equilibrium limitations and favors the formation of methanol. It also increases the rate of reaction, improving the efficiency of the process.


Why is the Haber process run at 450 degrees?

The Haber process is run at around 450 degrees Celsius to provide enough energy for the nitrogen (N2) and hydrogen (H2) molecules to overcome their activation energy and react to form ammonia (NH3). This temperature is a compromise between achieving a high reaction rate and minimizing production costs associated with operating at higher temperatures.


Does Haber Bosch process occur in a closed system?

The Haber Bosch system of making NH3 from Hydrogen and Nitrogen from the air came out in the early 1900's. Hydrogen and Air [78% Nitrogen] are combined together under very high pressure and basicly run over an Iron based plate [ the plate is the catalyst ] to form NH3. The very high pressures require a closed system. Previously all nitrates needed for the mfg. of explosives were mined from nitrate mines in Chilie. This invention unfortunatly greatly contributed to the destruction of WW1 The Haber Bosch system of making NH3 from Hydrogen and Nitrogen from the air came out in the early 1900's.

Is a basic proto slg 09 a high pressure gun?

It can be run on any pressure. Only low end mechanical guns "must" be high pressure, and only certain Angle markers "must" be run on low pressure.


Can you run in the air?

If air pressure is extremely high you could possibly run in the air. So probably at a really high elevation


Why rail pressure goes high when engine is on?

Engines need higher fuel pressure to start than they do to run.


How do you change high temperature refrigerant and high pressure refrigerant in to low temperature refrigerant and low pressure refrigerant?

You cool it and run it through a metering devise.


Can a spyder victor run on nitro?

Yes, but make sure you get a high output pressure tank.


What is good water pressure from a well?

The water pressure from a well is controlled by a pressure switch with a low setting of about 20 psi and a high setting of about 40 psi. It is adjustable for both high and low pressure and some wells, depending upon the pump capability will run from 40 psi low to 60 psi high.


Will a metal halide light run a high pressure sodium lamp?

yes No Rafe, it will not. Remember when you tried it.


Can ovarian cysts cause high blood pressure?

Ovarian cysts can cause high blood pressure in the sense that they can cause weaken a person's immune system and cause problems in the long run over time.
