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

Any information on this ?

What is the answer to the above question? Any chemistry help will be accepted. I am working on this question.

Expand  

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?

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

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