Use the following balanced equation to determine the partial pressure of water and the total pressure if 234 mL of methane (CH4) is combusted exactly (no LR) at 564 C in a container at a pressure of 2.44 atm.

CH4 (g) + 2O2 (g) --> CO2 (g) + 2H2O (g)

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

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
