How do you tell if a reaction is favorable or unfavorable?

To find if a reaction is favorable/spontaneous, you need to calculate ΔG. If ΔG is negative, then the reaction is favorable.

What is the Gibbs free energy at equilibrium?

Until it reaches a minimum value at the minimum value of Gibbs free energy the reaction is at equilibrium.

What is the relationship of the temperature with the calculated ΔH?

When the temperature increases, the amount of molecular interactions also increases. When the number of interactions increase, then the internal energy of the system rises. According to the first equation given, if the internal energy (U) increases then the ΔH increases as temperature rises.

Which is favorable exothermic or endothermic?

Reactions that do not require energy are seen as more favorable. Since exothermic reactions release energy and endothermic reactions require energy, exothermic reactions are more favorable.

What is favorable reaction?

Re: Favorable Reactions Kinetically favorable means that the there is a large difference for activation energy so more products than reactants. Thermodynamically favorable means that there is a negative delta G meaning more reactants than products.

How do you calculate the enthalpy of a mole?

To calculate the enthalpy of solution (heat of solution) using experimental data:

1. Amount of energy released or absorbed is calculated. q = m × Cg × ΔT. q = amount of energy released or absorbed.
2. calculate moles of solute. n = m ÷ M.
3. Amount of energy (heat) released or absorbed per mole of solute is calculated. ΔHsoln = q ÷ n.

What is s in chemistry?

(s) indicates that the substance is in a solid state. an alternative way of representing a substance in a solid state. (aq)

What is the final equilibrium temperature of the mixture?

Equal quantities of hot and cold water are mixed in the calorimeter and the final equilibrium temperature is measured. If the calorimeter absorbs no heat at all, the equilibrium temperature of the mixture is the average of the hot and cold temperatures.

What is the enthalpy of combustion of one mole of carbon?

In this case, the combustion of one mole of carbon has ∆H = −394 kJ/mol (this happens six times in the reaction), the change in enthalpy for the combustion of one mole of hydrogen gas is ∆H = −286 kJ/mol (this happens three times) and the carbon dioxide and water intermediaries become benzene with an enthalpy change of ∆H = +3,267 kJ/mol.

How do you calculate the enthalpy of ionic sodium chloride?

∆H = H products − H reactants. The addition of a sodium ion to a chloride ion to form sodium chloride is an example of a reaction you can calculate this way. Ionic sodium has an enthalpy of −239.7 kJ/mol, and chloride ion has enthalpy −167.4 kJ/mol.

What is the enthalpy of melting for water?

For water, the enthalpy of melting is ∆H melting = 6.007 kJ/mol. Imagine that you heat ice from 250 Kelvin until it melts, and then heat the water to 300 K. The enthalpy change for the heating parts is just the heat required, so you can find it using:
