under reduced pressure

This alternative is a common and direct synonym, focusing on the condition of pressure being lessened.

at decreased pressures

This option uses a slightly different adjective to describe the pressure, but the meaning remains very close.

under diminished pressure

This alternative emphasizes the state of pressure being reduced or lessened.

in conditions of low pressure

This alternative rephrases the concept as a description of specific conditions.

with lessened pressure

This highlights the action on the pressure to make it 'lessened'.

when the pressure is low

This alternative rephrases the concept as a conditional statement, specifying the condition under which the pressure is low.

FAQs

How can I use "at lower pressures" in a sentence?

You can use "at lower pressures" to describe conditions where pressure is reduced, such as in experiments or industrial processes. For example: "The reaction proceeds more efficiently "at lower pressures" because the activation energy is reduced."

What are some alternatives to "at lower pressures"?

Some alternatives include phrases like "under reduced pressure", "under diminished pressure", or "in conditions of low pressure". The best choice depends on the specific context and desired level of formality.

Is it correct to say "at low pressures" instead of "at lower pressures"?

While "at low pressures" is grammatically correct, "at lower pressures" implies a comparison to a higher pressure, either explicitly stated or implicitly understood. If no comparison is intended, "at low pressures" might be more appropriate.

What is the significance of performing a reaction "at lower pressures"?

Performing a reaction "at lower pressures" can affect reaction rates, equilibrium constants, and product yields. It's often done to favor certain reaction pathways or to reduce the risk of explosions.
