Rate law and Rate Constant
question_answer
For a reaction \[A\to B\], the rate of reaction quadrupled when the concentration of A is doubled. The rate expression of the reaction is \[r=K{{(A)}^{n}}\]. when the value of \[n\] is
A) 1
B) 0
C) 3
D) 2
Correct Answer:
D
Solution :
Rate of reaction is quadrupled on doubling the concentration. Thus \[r\propto \,{{[A]}^{2}}\].
