Molar gas constant

To find a factor to convert L-atm to J, we can equate two values of the molar gas constant, R... 

If there is exactly 1 mol of gas, the pressure is expressed in pascals (Pa), the temperature is in kelvin and the volume is in cubic metres (both SI units), then the value of the constant is 8.314 JK-1 mol-1. We call it the gas constant and give it the symbol R. (Some old books may call R the universal gas constant , molar gas constant or just the gas constant . You will find a discussion about R on p. 54) More generally, Equation (1.12) is rewritten as... 

The standard enthalpy difference between reactant(s) of a reaction and the activated complex in the transition state at the same temperature and pressure. It is symbolized by AH and is equal to (E - RT), where E is the energy of activation, R is the molar gas constant, and T is the absolute temperature (provided that all non-first-order rate constants are expressed in temperature-independent concentration units, such as molarity, and are measured at a fixed temperature and pressure). Formally, this quantity is the enthalpy of activation at constant pressure. See Transition-State Theory (Thermodynamics) Transition-State Theory Gibbs Free Energy of Activation Entropy of Activation Volume of Activation... 

The osmotic pressure, at constant temperature, of a dilute solution is proportional to the concentrations of the dissolved substances i.e., U = RTXc, where II is the osmotic pressure, R is the molar gas constant, T is the absolute temperature and Ci is the molar concentration of species i. 2. In stereochemistry, all optically active molecules contain one or more multivalent atoms united... 

A quantity (symbolized by AV or A V ) derived from the pressure dependence of a reaction rate constant Ay = -RT(dlnk/dF)j where R is the molar gas constant, T is the absolute temperature, k is the reaction rate constant, and P is pressure. For this equation, the rate constants of all non-first-order reactions are expressed in pressure-independent units (e.g., molarity) at a fixed temperature and pressure. 

Values recommended by the Committee on Data for Science and Technology (CODATA) Task Force on Fundamental Constants see E. R. Cohen and B. N. Taylor, J. Phys. Chem. Ref. Data 17, 1795-1803 (1988). Numbers in parentheses represent uncertainty in the last decimal places. For example, the uncertainty in the molar gas constant R is 0.000070 J K-1 mol-1.
