Please explain your answer!!! (Just QUESTION 60)
Which of the following changes will affect the activation energy of a reaction? Increasing or decreasing the reaction temperature. Adding a catalyst. Increasing or decreasing the reactant concentrations. The reaction CHCl3(g) + Cl2(g) rightarrow CCL4(g) + HCl(g) has been proposed to occur by the following mechanism. What is the rate law predicted by this mechanism? Cl2 2Cl fast qulibrium CHCI3 + Cl rightarrow HC1 + CCl3 slow step CCl3+Cl rightarrow CCl4 fast what is the rate law predicted by this mechanism Rate = k3[CCl3][Cl] Rate = k2(k1/k.1)1/2[CHCl3][Cl2]1/2 Rate = k2[CHCl3][Cl] Rate=k1[cl2] Rate=kexp[CHCl3][cl2]Explanation / Answer
rate depends solely on the slow step
here it is k2
so the answer will be c) rate = k2 [ CHCL3] [Cl}
