A) -1
B) -2
C) 1
D) 2
Correct Answer: B
Solution :
\[A+B\xrightarrow[{}]{{}}\Pr oduct\] \[Rate\,\propto \,\,[A]\,{{[B]}^{-2}}....(i)\] The rate decreases by factor 4 if the concentration of reactant ?B? is doubled So Rate \[\propto \,\,\,[A]\,{{[2B]}^{-2}}\] \[\propto \,\,\,\frac{[A]\,{{[B]}^{-2}}}{4}....(ii)\] Hence, order of reaction w.r.t. reactant B is -2.You need to login to perform this action.
