By this means, a catalyst is produced which is readily reduced at 300Â°C - 350Â°C (570 - 660OF) but with which loss of activity caused by sintering is not a problem during several years, normal operation at temperatures up to 350Â°C (660OF).
Temperature. As the temperature rises, reacting molecules have more and more kinetic energy. This increases the chances of a successful collision and so the rate increases. There is a certain temperature at which an enzyme's catalytic activity is at its greatest (see graph).
