What have you got so far? Can you show your work?

Hydrogen, Acetylene and ethane are all gases at STP so 0.1M is an unusual way to measure concentration.

Any information on this ?

Ask yourself: what is the dependence of the rate on the concentration of hydrogen? And what is the dependence of the rate on the concentration of ethyne?

And take it from there. 

What do you think?

[math]2H_2+C_2H_2 \rightarrow C_2H_6[/math]  is first order with respect to [math]H_2[/math] and zero order with respect to ethyne and the rate law is 

[math]Rate=k[H_2],k=\frac{rate}{[H2]}=\frac{1.0 \times 10^{−4}M/min}{0.1M} =1×10^{−3}min^{−1}[/math]
