Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.

One student said that the investigation was not valid (a fair test). write a plan for the investigation that includes improvements to the method and apparatus
