The rate of reaction between two reactants A and B decreases by a factor of 4 if the concentration of reactant B is doubled. The order of this reaction iwth respect is reactant B is:
Options
- A2
- B-2
- C1
- D-1
Correct answer
B. -2
Step-by-step solution
Rate of reaction = K [ A ₀ ]^ [ B ₀ ]^ aligned [ B ] & =2 [ ~B ₀ ] r₁ r₂ & = K [ A ₀ ]^ [ B ₀ ]^ [ A ₀ ]^ [2 ~B ₀ ]^ ; 4 & = ( 1 2 )^ = =-2 . aligned
