The following notation applies for all 1/T vs. ln Kred plots:

Filled symbols represent stable reactants, empty symbols represent stable products.

Hatched symbols represent experiments with no observed reaction.

Cross hatched symbols are for reported equilibria.

The number of corners of a symbols gives information on the pressure (circles 100 MPa, two circles 200 MPa, triangle 300 MPa, square 400 MPa etc.).
