Reaction kinetics — practice question

Which equation shows a correct propagation step in the chlorination of ethane?

  • A$\text{C}_2\text{H}_5\text{Cl} + \text{Cl}\cdot \rightarrow \text{C}_2\text{H}_4\text{Cl}\cdot + \text{HCl}$
  • B$\text{C}_2\text{H}_6 + \text{Cl}\cdot \rightarrow \text{C}_2\text{H}_5\text{Cl} + \text{H}\cdot$
  • C$\text{C}_2\text{H}_5\text{Cl} + \text{H}\cdot \rightarrow \text{C}_2\text{H}_5\cdot + \text{HCl}$
  • D$\text{C}_2\text{H}_5\cdot + \text{Cl}\cdot \rightarrow \text{C}_2\text{H}_5\text{Cl}$
