Standard conditions and integration times for calorimetry reactions.

Reaction	Inner Chamber	Outer Chamber	Integration time
Fe^II(H₂bip) + TEMPO ^a	2.8 mM Fe^II(H₂bip)	23 − 109 mM TEMPO ^a	∼ 10000 s
Ru^II(py-imH) + ^tBu₃PhO^•	5 − 10 mM Ru^II(py-imH)	11 mM ^tBu₃PhO^•	∼ 2000 s
Ru^II(py-imH) + TEMPO	10 mM Ru^II(py-imH)	11 mM TEMPO	∼ 4000 s
Co^II(H₂bim) + ^tBu₃PhO^•	6.2 mM Co^II(H₂bim)	4.4 mM ^tBu₃PhO^•	∼ 8000 s
TEMPOH + ^tBu₃PhO^•	11 mM TEMPOH	14.7 mM ^tBu₃PhO^•	∼ 4000 s

At 29.6 °C, Fe^II(H₂bip) + TEMPO has K_eq = 1.7 ± 0.3. In order to ensure that the reaction went to completion, 8 − 34 equiv of TEMPO were used.
