Question

How do I calculate $∆\mathrm{G}$?

Answer 1

To calculate delta G:

1. Gibbs free energy is the energy which is used to calculate the amount of work done in a thermodynamic system where temperature and pressure are constant.
2. To calculate Gibbs free energy, Change in free energy$\left(\mathrm{\Delta G}\right)$$=$ Change in enthalpy$\left(\mathrm{\Delta H}\right)$$–$ Product of temperature$\left(\mathrm{T}\right)$ and change in entropy$\left(\mathrm{\Delta S}\right)$. The equation is $(\mathrm{\Delta G}=\mathrm{\Delta H}–\mathrm{T\Delta S})$.

Thus,$\left(\mathrm{\Delta G}\right)$ can be calculated by using this formula $(\mathrm{\Delta G}=\mathrm{\Delta H}–\mathrm{T\Delta S})$.
