Question

A chemical reaction was carried out at 300 K and 280 K. The rate constants were found to be k1 and k2 respectively. Then (A) k2 = 4k1 (B) k2 = 2k1 (C) k2 = 0.25 k1 (D) k2 = 0.5 k1

For every 10° rise in temperture, Rate gets double. Hence, in this case rate constant will become four time. (d) i.e., k1 = 4k2 k2 = 0.25k1 as the Rise in temperature given is 20°C

Q. A chemical reaction was carried out at $300 K$ and $280 K$ . The rate constants were found to be $k_{1}$ and $k_{2}$ respectively. Then

$k_{2} = 4 k_{1}$

$k_{2} = 2 k_{1}$

$k_{2} = 0.25 k_{1}$

$k_{2} = 0.5 k_{1}$

For every $1 0^{\circ}$ rise in temperture, Rate gets double. Hence, in this case rate constant will become four time. (d) i.e.,
$k_{1} = 4 k_{2}$
$k_{2} = 0.25 k_{1}$
as the Rise in temperature given is $2 0^{\circ} C$

Q. A chemical reaction was carried out at 300K and 280K. The rate constants were found to be k1​ and k2​ respectively. Then

k2​=4k1​

k2​=2k1​

k2​=0.25k1​

k2​=0.5k1​
