Consider the following standard electrode potentials ( E o in volts) in aqueous solution: E l e m e n t _ M 3 + / M _ M + / M _ A l - 1.66 + 0.55 T l + 1.26 - 0.34 Based on these data, which of the following statements is correct?
Options
- AT l + is more stable than A l 3 +
- BA l + is more stable than A l 3 +
- CT l 3 + is more stable than A l 3 +
- DT l + is more stable than A l +
Correct answer
D. T l + is more stable than A l +
Step-by-step solution
∆ G o = - n F E o if E o = p o s i t i v e ; then ∆ G o = n e g a t i v e , For those conversions whose E o values are more positive are more favourable.
