What is the gas constant in ideal gas law?
Gas Constant Definition. The Gas Constant is the physical constant in the equation for the Ideal Gas Law: where P is pressure, V is volume, n is number of moles, and T is temperature. It’s also found in the Nernst equation relating the reduction potential of a half-cell to the standard electrode potential:
What is the formula of the gas constant from the equation?
The formula of the gas constant from the ideal gas law equation is and the T is the temperature in the kelvin. The SI unit of the ideal gas constant can be determined as: The SI unit of pressure is Pa or N m 鈭?. Now, N m is the equivalent to the joule, which is the SI unit of energy.
What is the unit of the gas constant?
Units for the gas constant vary, depending on other units used in the equation. One common value is 8.3145 J/molK.
