A 3.00 L cylinder at 25 degrees Celsius contains a mixture of 3 gases: He, N2, and Ar at partial pressures of 115, 285, and 325 torr, respectively. If all the He is removed from the mixture and the temperature does not change, what will be the partial pressure, in torr, of the N2

Butadiene undergoes a reaction at a certain temperature in the gas phase as follows: 2c4h6(g) --> c8h12(g) the following data were collected for this reaction: time (min) [c4h6] (m) 0 0.36 15 0.30 30 0.25 48 0.19 75 0. determine the order of the reaction and the rate constant. 1st order and k = 4.3x10 -4 s-1 1st order and k = 2.3x10-4 s-1 2nd order and k = 4.3x10-4 s-1 2nd order and k = 2.3x10-4 s-1 zero and k = 4.3x10-4 s-1
