Match the statements in Column 1 with the descriptions in Column 2.
| Column 1 | Column 2 |
| P Catalyst alters reaction rate | 1 Cannot be fractional or zero |
| Q Molecularity | 2 Proper orientation is not always present |
| R Second half-life of a first-order reaction | 3 By lowering activation energy |
| S e^(−Eₐ/RT) | 4 Same as the first half-life |
| T Energetically favourable reactions are sometimes slow | 5 Total probability is one |
| U Area under the Maxwell–Boltzmann curve is constant | 6 Fraction of molecules with energy at or above activation energy |
Options:
Answer:
A
Solution:
A catalyst lowers activation energy (P-3); molecularity counts particles (Q-1); first-order half-lives are equal (R-4); the Arrhenius exponential tracks the activated fraction (S-6); orientation can limit favourable reactions (T-2); normalized probability integrates to one (U-5).
