Asmall quantity of the inert gas argon (ar) is added to incandescent light bulbs to reduce vaporization of tungsten (w) atoms from the solid filament. what volume of argon gas measured at 760 mmhg is needed to fill a 0.21-l light bulb at a pressure of 1.30 mmhg? assume the argon gas temperature remains constant.

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
