Which of the following is the Clausius-Clapeyron Equation ?
Correct answer: C. loge (p/p0) = (λ/R) (1/T0 - 1/T)
- A. PV = RT + B/V + y/V2 + ....
- B. (P + a/V2)(V-b) = RT
- C. loge (p/p0) = (λ/R) (1/T0 - 1/T)
- D. p = [RT/(V - b)] - (a/TV2)
Explanation
The integrated Clausius-Clapeyron equation relates vapour pressures at two temperatures through latent heat, giving ln(p/p0) = (λ/R)(1/T0 − 1/T) when λ is treated as constant. The other expressions are virial or van der Waals-type equations of state.
