The Gas Constant (R) appears in many formulas including the following:

• Ideal Gas Law: PV = n[Private Equation]T     (Click any Parameter)
  • P = n•R•T / V : Ideal Gas Law solved for pressure.
  • V = n•R•T / P : Ideal Gas Law solved for volume.
  • n = (P•V)/(R•T) : Ideal Gas Law solved for number of mole.
  • T = (P•V)/(n•R) : Ideal Gas Law solved for temperature.

• Activation Energy:  `E_a = (R*T_1*T_2)/(T_1 - T_2) ln(k_1/k_2)`

• Arrhenius Equation:  `k = Ae^(E_a/(RT))`

• Barometric Formula (Troposphere): `p = p_0*(1 - (L*h)/T_0)^((g*M)/(R*L))`

• Clausius-Clapeyron Equation:  `ln(P_2/P_1) = (DeltaH_(vap))/R * (1/T_1 - 1/T_2)`

• Compressibility Factor:  `Z = (p*V_m)/(R*T)`

• Peng-Robinson Equation of State:  `p = (R*T)/(V_m - b) - (a*alpha)/(V_m^2 + 2*b*V_m - b^2)`

• Reduced Specific Volume:  `v_r = v/(R* (T_cr)/P_c)`

• Van't Hoff Equation:  `ΔH^0 = R * ( -ln(K_2/K_1))/ (1/T_1 - 1/T_2)`

• Root-mean-square Speed: [Private Equation]
