Web7 apr. 2024 · As the kinetic diameter of D 2 O (265 pm) is close to that of He (260 pm), [ 19] we can assume for D 2 O nearly the same Ediff value as experimentally obtained for He (see Figure 2d ). The reported values of Δ Hads for water on carbon materials are in the range from -45 to -69 kJ mol −1. [ 20] WebSince l has been shown to be roughly 2.0 × 10 -5 cm, d could be calculated if N / V was known. It is relatively easy to find ( N / V) d3, from which both d and N / V can be determined.
