WT5BZ] One method and the associated experimental device to study the temperature change Δ t rea in some gas sensor or material during sensing reaction are proposed. The formula of Δ t rea versus gas concentration and the relational expression of reaction exothermic rate P rea versus Δ t rea are given. The rate equation of surface reaction r and the surface reaction probability are discussed.
