The　upscaling　process　of　multicomponent　mass　transfer　and　reaction　in　a　rigid　and　homogeneous　porous　media　was　carried　out　using　the　method　of　volume　averaging.　The　first-order　reversible　reaction　which　occurs　at　the　solid-fluid　interface　was　considered　in　this　paper.　The　corresponding　macroscopic　governing　equations　were　derived　from　the　system　dynamics　at　the　pore　scale.　The　effective　coefficients　were　obtained　by　solving　the　associated　closure　problems.　This　study　shows　that　if　the　backward　reaction　rate　constant　at　the　microscale　is　small　enough,　i.e.　k(-)　-＞　0,　the　obtained　upscaled　model　is　in　accordance　with　the　macroscopic　model　derived　from　the　first-order　irreversible　heterogeneous　reaction　case　which　was　extensively　investigated　in　the　literature.　The　influence　of　reaction　rates　on　the　effective　parameters　in　the　macroscopic　equations　was　also　investigated.　It　has　been　found　that　both　forward　and　backward　reaction　rates　have　significant　influence　on　the　effective　diffusivities　and　effective　reaction　rates　in　the　macroscopic　equations.　The　established　equations　were　successfully　verified　by　the　comparison　of　the　direct　numerical　calculations.　(C)　2017　Elsevier　Ltd.　All　rights　reserved.
