According to the reactivity series, copper is below hydrogen.
In theory, hydrogen gas should be able to displace copper in a copper(II) chloride solution should the gas be bubbled into the solution, is this true?

Is copper below hydrogen or hydrogen gas (H2)?

Touche... it is hydrogen.
But how can I find out if hydrogen gas is more reactive than copper? Gases are often more unstable and reactive than solids is it not?

I agree that Hydrogen is more reactive than Copper. Heat solid CuCl2 (below its temperature of decomposition) and pass H2 gas over it. I would expect:

CuCl2 + H2 --> Cu + 2 HCl
