To make compost tea you just need a covered container, compost, water, and time. I use a cotton pillowcase or a square of unbleached cotton. I move the bundle up and down a few times whenever I walk by the container.
More generally, the terms exergonic and endergonic relate to the free energy change in any process, not just chemical reactions. An example of an exergonic reaction is cellular respiration. By contrast, the terms exothermic and endothermic relate to the overall exchange of heat during a process.
Spontaneous processes are processes that occur without any outside intervention. Spontaneous processes have a definite direction. For example methane once lit burns producing CO 2(g) and H 2 O (g) without intervention, however, CO 2(g) and H 2 O (g) don't combine to make methane and oxygen without outside intervention.or example the process of water freezing is only spontaneous when the temperature is less then 0Â° C. When water is at a temperature above 0Â° C the process of freezing is no longer spontaneous. However, when the temperature = 0Â° C the solid and liquid phases are in equilibrium.
