activation energy for sodium thiosulfate and hcl reaction

hey, so i found the activation energy to be 42.9kJ but im looking for a source that states the actual value. ik its somewhere around 47kJ but i havent found a good source for it

btw the clock reaction is the one im talking about. more specifically: Na2S2O3(aq) + 2HCl(aq) → S(s) + SO2(g) + 2NaCl(aq)

This reaction measures the rate as an average over the time period.
You would have to make an adjustment to the concentration before attempting to determine the rate constant at each temperature.
