For a chemical reaction A→BA \to B, it was found that concentration of BB is increased by 0.2molL−10 . 2mol{L}^{- 1} in 30 min. The average rate of the reaction is ________ ×10−1molL−1h−1\times {10}^{- 1}mol{L}^{- 1}{h}^{- 1}. (in nearest integer)

Correct answer

0

Step-by-step solution

A⟶BA ⟶ B

t=00t = 00

t=30min0.2Mt = 30min0 . 2M

Av. rate of reaction =−Δ[A]\Deltat=Δ[B]\Deltat=(0.2−0)12= - \dfrac{\Delta [ A ]}{\Deltat} = \dfrac{\Delta [ B ]}{\Deltat} = \dfrac{( 0 . 2 - 0 )}{\dfrac{1}{2}}

=0.4=4×10−1mol/L×hr= 0 . 4 = 4 \times {10}^{- 1}mol / L \times hr
