Question

The first order rate constant is expressed as $ K=\frac{2.303}{t}\log ({{C}_{0}}/{{C}_{t}}) $ while $ K $ depends on

• A. time $ (t) $
• B. initial concentration of the reactant $ ({{C}_{0}}) $
• C. the ratio $ {{C}_{0}}/{{C}_{t}} $
• D. all of these

Answer 1

Answer: (D)

: For first order reaction, $ K=\frac{2.303}{t}\log \frac{{{C}_{0}}}{{{C}_{t}}} $ $ {{C}_{0}}= $ Initial concentration $ {{C}_{t}}= $ Concentration at time $ t $ rate constant depends on temperature.
