Please help me solve this sooner rather than later. ​

Which produce would best increase the amount of heat energy that is actually gained by calorimeter b

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.
