Please Help! Extra Credit assignment due soon! Why is the variable R used as the universal gas constant as apposed to another other letter or symbol?
The value of the universal gas constant, R, is approximately 8.3145 joules per mole-kelvin (J/mol·K) or 0.0821 liter-atmospheres per mole-kelvin (L·atm/mol·K).
The variable R is significant because it represents the proportionality constant in the ideal gas law, which describes the relationship between the pressure, volume, temperature, and number of moles of an ideal gas.
No, the value of R is not constant for all gases. It varies depending on the units used for pressure, volume, and temperature. It also changes for different gas laws, such as the ideal gas law and the van der Waals equation.
The value of R can be determined experimentally by measuring the pressure, volume, temperature, and number of moles of an ideal gas under known conditions and using these values in the ideal gas law to calculate R.
No, the value of R is only applicable to ideal gases. For non-ideal gases, other variables such as intermolecular forces and molecular size must be taken into account, and the value of R may vary depending on the specific gas law used.
