Question

For a reaction $E_a$ = and $K=3.2\times {10}^4{S}^{-1}$ at 300 k.

• A. $6.4\times {10}^4{S}^{-1}$
• B. $3.2\times {10}^4{S}^{-1}$
• C. $3.2\times {10}^8{S}^{-1}$
• D. $3.2\times {10}^5{S}^{–1}$

Answer 1

The correct option is B $3.2\times {10}^4{S}^{-1}$

$K=A{e}^{\frac{-Ea}{RT}}{E}_a=0;K=A=$constant
$K_{310}=K_{300}=3.2\times {10}^4{S}^{-1}$
