How to find grams excess reactant?
The reactant that produces a larger amount of product is the excess reactant. To find the amount of remaining excess reactant, subtract the mass of excess reactant consumed from the total mass of excess reactant given.
Explanation:
Answer is:
Step 1: XY₂+ Z₂ → XY₂Z + Z <span>(slow).
Step 2: </span>XY₂+ Z → XY₂Z <span>(fast).
Overall reaction: step 1 + step 2:
</span>XY₂+ Z₂ + XY₂+ Z ⇌ XY₂Z + Z + XY₂Z.<span>
2XY</span>₂+Z₂ ⇌ 2XY₂Z.
<span>The sum of the two elementary steps is equivalent to the stoichiometric equation. Rate of chemical reaction depends on slow step (step 1).</span>
