For the reaction: C₂H₄Br₂ + 3 KI → C₂H₄ + 2 KBr + KI₃, when the rate of reaction is 2.0 × 10^-5, what is the rate of appearance of KBr?

Question

Quizplus · Accepted Answer

The stoichiometry of the reaction shows that 2 moles of KBr are produced for every mole of C2H4Br2 that reacts. Therefore, the rate of appearance of KBr is twice the rate of the reaction, which is 2 × 2.0 × 10^-5 = 4.0 × 10^-5.

For the Reaction: C2H4Br2 + 3 KI → C2H4

For the Reaction: C₂H₄Br₂ + 3 KI → C₂H₄
