Any bibliographic database? I've put TITLE-ABS-KEY ("hydrochloric" AND
"magnesium" AND "activation energy") into Scopus and I got this:
J.P. Birk, D.L. Walters, Pressure measurements to determine the rate law of
the magnesium-hydrochloric acid reaction, J Chem Educ 70 (1993) 587-589
<
https://doi.org/10.1021/ed070p587>
They give the result of example activation energy experiment as 33.8 kJ/mol.
