A) \[1.28\times {{10}^{-2}}\]
B) \[6.4\times {{10}^{-3}}\]
C) \[9.6\times {{10}^{-3}}\]
D) \[3.2\times {{10}^{-4}}\]
Correct Answer: B
Solution :
As we know that the velocity constant become double by increasing the temperature by 10°C so if at 290 K, velocity constant \[=3.2\times {{10}^{-3}}\] then at 300 K, velocity constant \[=2({{K}_{290}})\]\[=2\times 3.2\times {{10}^{-3}}\]\[=6.4\times {{10}^{-3}}\].
