Consider the first-order reaction A → B in which A molecules (shaded spheres)are converted to B molecules (unshaded spheres).
-Which drawing (a)-(d)represents the reaction mixture at t = 3 minutes?

Question

Consider the first-order reaction A → B in which A molecules (shaded spheres)are converted to B molecules (unshaded spheres). 
-Which drawing (a)-(d)represents the reaction mixture at t = 3 minutes?

Quizplus · Accepted Answer

Drawing (c) accurately represents the reaction mixture at t = 3 minutes because it shows an intermediate stage of the reaction where reactants are partially converted into products, consistent with the expected progression of a reaction over time.
