Help please asap. chem sucks

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

Define the kinetic molecular theory

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.
