← ScienceWhich outcome occurs when a salt bridge is omitted from a zinc-copper electrochemical cell operating at standard conditions?
A)Electron flow quickly ceases✓
B)Voltage remains stable, decreases slightly
C)Reaction rate increases exponentially
D)Equilibrium shifts toward product formation
💡 Explanation
Electron flow ceases quickly because ions cannot flow between half-cells to maintain charge neutrality; thus, the buildup of charge prevents further redox reactions via charge separation, rather than leading to small voltage changes, electrochemical equilibrium, or exponential increase.
