What happens during an exothermic reaction

Heat is given off during an exothermic reaction. Heat is absorbed during an endothermic reaction

Which of the following shows that the combustion of methane produces 802 kJ mol of energy

CH4(g) + 2O2(g) CO2(g) + 2H2O(g) + 802 kJ/mol

What reactions would have a decrease in entropy

anabolic reaction

How do reaction involving gases affect the entropy of a system

Reactions involving gases can negate the entropy of a system. However, certain gases can increase the rate of entropy. Thus, some gases are considered beneficial and others negative.

What is S in the equation delta G equals delta H minus TdeltaS

S stands for entropy content.

What temperature would a reaction with H -220 kJmol and S -0.05 kJ(molK) be spontaneous
