Hint: The universal molar gas constant, commonly known as the gas constant, appears in an equation describing the behaviour of a gas under theoretically perfect conditions. R is the standard symbol for the gas constant.
Complete answer:
The gas constant, indicated by R, is a physical constant that is measured in units of energy per temperature increment per mole. Ideal gas constant, molar gas constant, and universal gas constant are all terms for the same thing. The gas constant is the same as the Boltzmann constant, however it is stated as the pressure-volume product rather than energy per temperature increment per particle.
The gas constant has been found, by experiment, to have a value of approximately 8.3145 joules per kelvin per mole (J · K-1 · mol-1).
The value of the universal gas constant is .
The specific gas constant is defined as the ratio of the molar gas constant (R) to the molar mass (M) of a gas mixture. can be mathematically expressed as:
With the help of the ideal gas equation, the gas constant can be expressed as:
P is the pressure
V is the volume
n is the number of moles of the given substance
T is the temperature.
The correct option is (a).
Note:
When one mole of particles at a defined temperature is examined, the gas constant is a proportionality constant used to connect the energy scale to the temperature scale. Boyle's law, Avogadro's number, Charles' law, and Gay-law Lussac's combine to form the ideal gas constant.
