Chemical Kinetics and Nuclear Chemistry question

2023 · 13 Apr · Shift 1 · Q16

JEE MainChemistryChemical Kinetics and Nuclear ChemistryNumerical+4 / −1
t87.5\mathrm{t}_{87.5}t87.5​ is the time required for the reaction to undergo 87.5%87.5 \%87.5% completion and t50\mathrm{t}_{50}t50​ is the time required for the reaction to undergo 50%50 \%50% completion. The relation between t87.5\mathrm{t}_{87.5}t87.5​ and t50\mathrm{t}_{50}t50​ for a first order reaction is t87.5=x×t50\mathrm{t}_{87.5}=x \times \mathrm{t}_{50}t87.5​=x×t50​ The value of xxx is ‾\underline{\hspace{2cm}}​.
