In a balanced chemical equation, we have two numbers that indicate two different factors. The definitions of these numbers are as follows:
1- Molar ratio: This ratio represents the ratio between the number of moles of any two substances in the balanced equation
2- The coefficients in the balanced chemical equation: These numbers represent the numbers of particles of each of the substances taking place in this chemical equation.
The answer is b, because if it gets colder then means more heat is exiting than it is entering.
Answer:
Gibbs equation helps us to predict the spontaneity of reaction on the basis of enthalpy and entropy values directly. When the reaction is exothermic, enthalpy of the system is negative making Gibbs free energy negative. Hence, we can say that all exothermic reactions are spontaneous.
