Chemical Kinetics Question 332
Question: 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
Options:
A) $ k_2=4k_1 $
B) $ k_2=2k_1 $
C) $ k_2=0.25,k_1 $
D) $ k_2=0.5k_1 $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] The rate constant doubles for $ 10{}^\circ C $ rise in temperature. For $ 20{}^\circ C $ rise, the rate constant will be 4 times
$ \therefore k_1=4k_2or,k_2=0.25k_1 $
