The equation of state for a non-ideal gas is 𝑃𝑣 𝑅𝑇= 1 + 𝐡𝑃 where 𝑃 is pressure, 𝑣 is specific volume, 𝑅 is the specific gas constant, 𝑇 is temperature, and 𝐡 is a temperature dependent parameter. For this gas, the partial derivative of enthalpy with respect to pressure at constant temperature is

  • A. 𝐡𝑅𝑇
  • B. βˆ’π‘…π‘‡2 (𝑑𝐡 𝑑𝑇)
  • C. π΅π‘…π‘‡βˆ’π‘…π‘‡2 (𝑑𝐡 𝑑𝑇)
  • D. 0

Answer: B. βˆ’π‘…π‘‡2 (𝑑𝐡 𝑑𝑇)
