URGENT: Consider this system at equilibrium: 2SO2(g) + O2(g) <==> 2SO3(g) + heat

How will each of the following changes affect an equilibrium mixture of the three gases (shift right, shift left, or no change)?

a. increase the concentration of O2
b. increase the concentration of SO3
c. chill the reaction
d. add a catalyst
e. reduce the concentration of SO2

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
