A) \[{{k}_{2}}=4{{k}_{1}}\]
B) \[{{k}_{2}}=2{{k}_{1}}\]
C) \[{{k}_{2}}=0.25{{k}_{1}}\]
D) \[{{k}_{2}}=0.5{{k}_{1}}\]
Correct Answer: C
Solution :
For every \[10{}^\circ \] rise in temperature, rate constant, k is doubled. Hence, for \[{{20}^{o}}\] rise, the rate constant will be four times, ie, \[{{k}_{1}}=4{{k}_{2}}\] \[{{k}_{2}}=\frac{1}{4}{{k}_{1}}\] \[=0.25{{k}_{1}}\]You need to login to perform this action.
