A reactant. Q. decomposes at a second order. The slope of the graph 1/[Q] (1/M) vs time (s) is -0.04556. If the initial concentration of Q for the reaction is 0.50 M, what is the concentration in M. of Q after 10.0 minutes?

They are all full and don't need any more electrons in there outer shell.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
