Title:

Kinetic Modeling of Plasma Methane Conversion using Gliding Arc

Specific comments:(use additional pages if needed) The paper investigated the methane conversion using Gliding Arc. The topic is interesting and novel in some degree. I recommend the paper published in JNGC. For the following questions please the author would like to thinking. (1) Please the author gives the meaning of n, k in equation (5). (2) There is a spelling mistake in “ΔHf, reactan” in equation (6). n

(3) In Table 1, what’s the meaning of the sentence of “ k = AT exp(− E / RTr ) , in cm, kJ, s, and mole units”.

And what are the units of A, n, E in Table 1. (4) There are some mistakes in Figure 6, 7. In Figure 6, the figure (d) is designated as (b), please revise it; In Figure 7, the Figure 7(c) is designated as Figure 7(b), please revise it. (5) The unit of flow rate (Nl/min), please revise it to L/min.
