WebThis right here is in joules. So if we want to write everything in kilojoules, since we already wrote that down, let's write this in kilojoules. So it's 0.242 kilojoules per Kelvin. And so now our Gibbs free energy right here is going to be minus 890 kilojoules minus 290-- so the minus and the minus, you get a plus. Webthe ΔH and ΔS can be calculated based on the linear equation obtained from the linear fitting of the graph. The second way to calculate the ΔS is by using Equation 4. Once ΔG and ΔH are known from Equation 3 and the slope of the linear graph, ΔS can be calculated with temperature in Kelvin. 3. Examples Example 1. At 0°C, one liter of ...
