Question

Rate law for the reaction `A + 2B rarr C`, is found to be Rate = k [A] [B]. If the concentration of reactant B is doubled keeping the concentration of A constant, the value of rate constant will be
A. the same
B. doubled
C. quadrupled
D. halved

Answer 1

Correct Answer - B
Rate of reaction, `r_(1)=k[A][B]`
`r_(2)=k[A][2B]`
`r_(2)=2r_(1)`
