Calculated activation energy seems to be wrong.

dear professor.

I used Cl-NEB calculation for H2O dissociation on Pt(111).

Then forces were well converge. (At first, IBRION = 3 and POTIM = 0.01 and then IBRION = 1, POTIM = 0.1)

Calculated activation barrier which is estimated by cl-NEB is about 1.39 eV.

But the activation barrier of other references is about 0.75~0.80 eV.

My calculation results is attached.

I confirm ask you which part is wrong.

Thank you for your kindness.
