Ideal Gas Law constant

Ideal Gas Law constant, polymerization rate, mole/liter sec. 

In this equation, R is called the ideal gas law constant. Its value depends on the units used, but assuming pressure is measured in atmospheres, volume in liters, and temperature in Kelvins its value is 0.082 atm-L/mol-K. Other forms of the ideal gas law are... 

Q = heat energy provided as such to the fluid system from an outside source, ft lbf/lbm r = knuckle radius, in., see Table 4 r, = inside radius of shell, in., see Table 4 R = ideal-gas-law constant, 1545 (lbf/ft2Xft3)/(lb molX°R)... 

The overbars mean average. The k in the proportionality constant is called the Boltzmann constant. It is equal to R, the ideal gas law constant (with unfamiliar units), divided by Avogadro s number. Note that this k is the same for all gases. 

Calculate the values and units of the ideal gas law constant in any set of units from the standard conditions. 

Ideal Gas Law constant]—Some texts may use a different unit for one of the quantities, changing the apparent value of this constant. You can, however, convert back to the constant that we use in this book.
