The rate law for the reaction A + B → product is given by rate = k [ A ] [ B ] Calculate [ A ] if rate of reaction and rate constant are 0.25 mol dm − 3 s − 1 and 6.25 mol − 1 dm 3 s − 1 respectively

Question

The rate law for the reaction A + B → product is given by rate = k [ A ] [ B ] Calculate [ A ] if rate of reaction and rate constant are 0.25 mol dm − 3 s − 1 and 6.25 mol − 1 dm 3 s − 1 respectively [ [ B ] = 0.25 mol dm − 3 ]

TestHub · Accepted Answer

rate = k [ A ] [ B ] ∴ [ A ] = k [ B ] rate ​ ​ = 6.25 mol − 1 dm 3 s − 1 × 0.25 mol dm − 3 0.25 mol dm − 3 s − 1 ​ = 0.16 mol dm 3 ​
