Use the following diagram of a cell to answer questions
-In the cell shown above,A is a standard Ag⁺/Ag electrode connected to a standard hydrogen electrode (SHE) .If the voltmeter reading is +0.80 V,what is the equation for the cell reaction?

A) Ag(s) + H⁺(aq) $\rightarrow$ Ag⁺(aq) + ½H₂(g)
B) Ag⁺(aq) + ½H₂(g) $\rightarrow$ Ag(s) + H⁺(aq)
