As you may soon learn in thermodynamics, the reaction rate constant, k, depends on the activation energy, temperature and pressure (if gaseous) of the system. Therefore, to unify reaction rates and rate constants, a standard temperature and pressure (such as STP and SATP) is designated to make sure when one chemist publishes a certain set of results, it could be accurately reproduced using the exact same reaction circumstances.
What else can I help you with?
When is pressure useful?
when determining volume, moles, weight, and/or temperature
Do we need Mercury?
Do you mean as an industrial agent, or as some kind of nutrient? Mercury is very toxic and should not be ingested for any reason. The primary useful role for mercury is that it is the only metal that is a liquid at standard temperature and pressure.
Why is viscosity useful?
Technology design involve a knowledge of the flowing properties of materials. Viscosity is dependent on temperature and pressure.
What is the relationship between volume temperature and pressure that is useful for designing things with fixed-volume pistons?
You can use the ideal gas law: PV=RTn, where: P is the pressure V is the volume R is the proportionality constant, the so-called "gas constant" T is the absolute temperature n is the number of moles
What is a pressure of 101.3 equal to?
101.325 kPa is equivalent to one atmosphere of pressure, or 760 mm Hg. It is a very useful conversion factor.
What can standard measurements be useful for?
Standard measurements can be useful for having a set scale that all objects can be measured by. It allows for a common standard by which to judge objects.
What sample of matter sublimes at room temperature and stand and pressure?
Dry ice, which is solid carbon dioxide (CO₂), is a common example of a substance that sublimates at room temperature and standard pressure. At temperatures above -78.5°C (-109.3°F), it transitions directly from a solid to a gas without becoming liquid. This property makes dry ice useful for refrigeration and creating fog effects. Other substances that can sublime at room temperature include iodine and certain salts like ammonium chloride.
What would be the volume of 2mol of CH4 gas?
The answer would depend on the temperature and pressure. And since you have not bothered to share these crucial bits of information, I cannot provide a more useful answer.
What are the useful of standard unit in a market?
air
Why is a thermometer useful?
It can tell you if you have a temperature...
How is thermometer useful in future purpose?
it is very useful to check out our temperature...................................M.S
Why is it important to know the mass and volume of gas at STP?
Knowing the mass and volume of gas at STP (standard temperature and pressure) helps in calculating the number of moles of the gas present, which is useful in chemical reactions and stoichiometry calculations. Additionally, it allows for comparisons between different gases under standardized conditions.
