Figure 1: Arrhenius plots of (cm^{3} molecule^{−1} s^{−1}) for the forward thermal rate coefficients of the H + CH_{4} reaction against the reciprocal of temperature (K), in the range 250–1000 K. Black line: MCDTH quantum calculations on the CBE surface; red line: MCDTH quantum calculations on the WWM surface; blue line: quantum calculations on the ZBB2 surface; black dashed line: VTST/MT calculations on the CBE surface; crosses: experimental values [60].
