According to the Wikipedia page on the Nernst's equation, the change in Gibbs free energy is $$ \Delta G = \Delta G^\circ + kT\ln Q \tag{1} $$ But, according to many other sources and also to my book ...

When 0.45 g of Zn is added to 50.0 ml of 0.95 M HCl solution, the solution inside the calorimeter heats up by 12 °C. What is the molar enthalpy of the reaction (in kJ/mol)? I know how to find the ...

If you mix $\pu{20 ml}$ of $\pu{3 M}$ sugar solution with $\pu{30 ml}$ of a $\pu{5 M}$ sugar solution, what solution do you end up with? What I did, \begin{align} \text{volume} &= \frac{\text{...

I want to derive Gibbs Free Energy formula from 1st and 2nd law of thermodynamics. I saw some texts using T and P constant in derivation. I am confused about that. If n,P, T are constant then its ...

The problem statement, all variables and given/known data: A certain mass m of water in a copper pot is heated over a stove that releases Q joules of heat to heat the water. Later the same mass m of ...

Is there an equation to calculate the internal energy of a gas mixture, or is it too complicated to be computed so simply? I know that there's $E_{internal}=N(degrees of freedom)\frac12kT$ and $(P+a\...

Suppose I have two ionic compounds: "NaY" and "XCl". If these were both 'safe' to eat, would it be true that ...
