If ϕ denotes standard reduction potential, which is true:

View answer and explanation

Correct option: A

E_{\mathrm{cell}}^ \circ = {\phi _R} - {\phi _L}

Option A (

E_{\mathrm{cell}}^ \circ = {\phi _R} - {\phi _L}

) is correct because the standard cell potential is calculated by subtracting the standard reduction potential of the left-hand electrode (anode) from the standard reduction potential of the right-hand electrode (cathode).
