The Viking spacecraft explore the question of life elsewhere in our solar system. Exponential growth is introduced as a general characteristic of life under favorable conditions. This was the basis for one of the life-detection experiments on the Viking spacecraft landed on Mars. In the experiment, gas chromatography showed that O2 gas is formed when martian soil is exposed to water vapor. However, the rate of production doed not resemble exponential growth; an alternative reaction is proposed. Thus chemical rate behaviour distinguishes reaction types even on another planet many millions of miles away.
