The lab procedure you just read involved several factors, listed below. Some were variable, and
some were constant. Use the drop-down menus to
label each factor with V for variable or C for
constant.
molarity of HCl used as analyte
molarity of NaOH used as titrant
volume of HCI
volume of NaOH
temperature of HCI
temperature of NaOH

When will le chatelier's principle come into effect? at the beginning of a reaction, when there are only reactants when a reaction has reached chemical equilibrium when a catalyst is added to a reaction mixture when a reaction is occurring but not yet at equilibrium

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

Based on the equation and the information in the table, what is the enthalpy of the reaction?
