A batch reactor shows CA decreasing exponentially from 1 to near 0, while CR and CS increase identically (single overlapping curve) toward a plateau of ~0.5. Which reaction scheme (rate constants in s⁻¹) matches?
- AA⇌R (k=1,1) and A→S (k=1)
- BA⇌R (k=3,3) and A⇌S (k=1,1)
- A→R (k=1) and A→S (k=1)
- DA→R (k=1) and A→S (k=3)
Explanation
CR=CS identically at all times requires equal, one-way (irreversible) rate constants to both products with no reverse reactions: A→R(k=1), A→S(k=1).
