Butadiene C4H6, dimerizes according to the following reaction: C4H6(g)-->C8H12(g) The dimerization is a second-order reaction. It takes 103 s for the concentration of C4H6 to go from 0.310 M to 0.208 M. What is k for the dimerization? (in L/mol x s)

Given that the reaction 2 H2(g) + O2(g)-> 2 H₂O(g) is exothermic, which of the following is true of the reaction 2 H₂O(g) 2 H2(g) + O2(g)? Its activation energy is lower than that of 2 H2(g) + O2(g) -> 2 H₂O(g) Its activation energy is the same as that of 2 H2(g) + O2(g) -> 2 H₂O(g). Its activation energy is higher than that of 2 H2(g) + O2(g) ->2 H₂O(g)- O There is no relationship between its activation energy and that of 2 H2(g) + O2(g)-> 2 H₂O(g).

6. The gas phase reaction A+B C has a reaction rate which is experimentally observed to follow the relationship rate= k[A]2[B]. Which one of the following would affect the value of the specific rate constant, k? (a) increasing the temperature(b) changing the concentration of A (c) changing the concentration of B(d) changing the concentration of C (e) all of the above

Reaction to produce COCl2 (phosgene) from chlorine and carbon monoxide in a gaseous stateIt is said that the mechanism of is as follows.1st step: Cl2 ⇔ 2 Cl (Fast equilibrium)2nd step: Cl + CO ⇔ COCl (Fast equilibrium)3rd step: COCl + Cl2 ⇒ COCl2 + Cl (slow)4th step: 2 Cl ⇒ Cl2 (fast)Overall reaction: CO + Cl2 ⇒ COCl2Derive the rate law of this reaction.
