Use the following diagram of a cell to answer questions
-In the cell shown above,A is a standard Zn²⁺/Zn electrode connected to a standard hydrogen electrode (SHE) .If the voltmeter reading is -0.76 V,what is the equation for the cell reaction?

A) Zn²⁺(aq) + H₂(g) $\rightarrow$ Zn(s) + 2H⁺(aq)
B) Zn(s) + 2H⁺(aq) $\rightarrow$ Zn²⁺(aq) + H₂(g)
