MDCAT Chemistry MCQ #1000

1. Question 1

   Q1. In the reaction mechanism of H2 + I2 → 2HI, the rate law is...

   • A) Rate = k[H2][I2]
   • B) Rate = k[H2]²[I2]
   • C) Rate = k[I2]²
   • D) Rate = k[H2]²

   Answer: Rate = k[H2][I2]

   Explanation: Experimental data shows first-order dependence on both reactants. Options B-C are incorrect as they assume incorrect stoichiometry.
