Question

A zero-order reaction A -> B. At the end of 1 h, A is 75% reacted. How much of it will be left unreacted at the end of 2 h.

Prashant Kotian · Accepted Answer

Correct answer: D. Since 75% of the reactant reacts in 1 h, the time for 100% completion of the zero-order reaction is t = 1.0 h / 0.75 = 1.33 h. Therefore, at the end of 2 h, the reaction is completely finished, leaving 0% unreacted.
