“…Under flow of a constant current (constant reaction rate) the achieved potential is lower when a variable which favours the electrochemical reaction increases. This is the case for temperature (Garcia-Cordova et al, 2011;Ismail et al, 2011;Otero & Cortes, 2003b;Valero Conzuelo et al, 2010; or electrolyte concentration GarciaCordova et al, 2011;Otero & Cortes, 2003b;Otero et al, 2007b;Valero Conzuelo et al, 2010). On the other hand, the potential shifts to higher values when a variable makes the reaction harder: the muscle moves larger masses (Garcia-Cordova et al, 2011;Otero et al, 2007b;Valero Conzuelo et al, 2010) or moves the mass faster by applying now rising currents (Garcia-Cordova et al, 2011;Ismail et al, 2011;Valero et al, 2011).…”
