Exp. | [A] | [B] | Initial rate |
1 | \[0.012\] | \[0.035\] | \[0.1\] |
2 | \[0.024\] | \[0.070\] | \[0.8\] |
3 | \[0.024\] | \[0.035\] | \[0.1\] |
4 | \[0.012\] | \[0.070\] | \[0.8\] |
A) rate \[=k{{[B]}^{3}}\]
B) rate \[=k{{[B]}^{4}}\]
C) rate \[=k[A]\,{{[B]}^{3}}\]
D) rate \[=k{{[A]}^{2}}\,{{[B]}^{2}}\]
Correct Answer: A
Solution :
From data 1 and 3, it is clear that keeping [B] const, [A] is doubled, rate remains unaffected. Hence rate is independent of [A]. From 1 and 4, keeping [A] constant, [B] is doubled, rate become 8 times. Hence rate \[\propto {{[B]}^{3}}\]You need to login to perform this action.
