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.
