Equilibrium Constant Kc and How to Calculate It

WebGeneral chemistry students often use simple calorimeters constructed from polystyrene cups (Figure 5.12). These easy-to-use “coffee cup” calorimeters allow more heat exchange with the outside environment, and therefore produce less accurate energy values. ...
