Examples of Non-Equilibria Systems Flashcards
what is combustion?
Combustion is a redox reaction with a fuel and oxidant. It is an exothermic process that goes to completion and has a positive change in entropy.
Identify the entropies and enthalpies of combustion.
Enthaply is negative, as it is an exothermic reaction. The energy released from the formation of bonds is greater than the absorption of bonds.
Entropy is positive - more disorder occurs
What is enthalpy?
total measure of internal energy in a system
What is entropy?
A measure of disorder
What is photosynthesis?
Photosythesis is the reaction by which plant cells harness energy from the sun, and turn it into chemical energy. It is an endothermic process which goes to completion and has a negative change in entropy.
A reaction is non-sponateneous when…
Enthalpy is + and entropy is -
