Practice question
Question
The activation energy (Ea) estimated for a reaction from the Arrhenius equation is 21KJ mol ⁻¹ . If the frequency factor is assumed to be independent of temperature, then the ratio of the rate constants determined at 298 K and 260 K is (rounded off to two decimal places). (Given: Gas constant, R = 8.315 J K. ⁻¹ mo1 ⁻¹ )
Explanation
Understanding molecular bonding reveals hybridization and orbital overlap dictate geometry and reactivity. Therefore Option NAT is correct because it satisfies bonding and stability criteria, which underpins key processes in chemistry.
