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 ]

Question

Quantrex Academy · Accepted Answer

Correct answer: B. 0.16 ~mol dm ^3

aligned rate = k [ A ][ B ] & [ A ]= rate k [ B ] & = 0.25 ~mol dm ⁻³ ~s ⁻¹ 6.25 ~mol ⁻¹ dm ^3 ~s ⁻¹ 0.25 ~mol dm ⁻³ & =0.16 ~mol dm ^3 aligned
