“…The only technique known to‐date that can vary the heating rate of reaction systems over a wide range (10 2 –10 5 K/s) and directly measure the rate of species interaction is the so‐called electrothermography method, which was developed originally to study oxidation and catalytic processes (cf. Grigor'ev et al,1973; Rader and Weller,1974). This method was also utilized previously to investigate the kinetics of gas‐solid interactions (cf.…”
