Question

Three standard reduction electrode potentials are given as E(A)= -1.00 V for A+(aq)/A(s); E(B)= -0.50 V for B+(aq)/B(s); and E(c)= -0.25V for C+(aq)/C(s). Which of the following chemical reactions will spontaneously occur? Briefly explain.

Three standard reduction electrode potentials are given as E(A)= -1.00 V for A+(aq)/A(s); E(B)= -0.50 V for B+(aq)/B(s); and E(c)= -0.25V for C+(aq)/C(s). Which of the following chemical reactions will spontaneously occur? Briefly explain. (a) A(s) + B(s) - > A+(aq) + B+(aq) (b) A+(aq) + B+(aq) - > A(s) + B(s) (c) A(s) + B+(s) - > A+(s) + B(s) (d) C(s) + B+(aq) - > C+(aq) + B(s) (e) A(s) + C+(aq) - > A+(aq) + C(s) (f) A+(aq) + C(s) - > A(s) + C+(aq)

Explanation / Answer

(c) A(s) + B+(s)---------------->A+(s) + B(s)

(e) A(s) + C+(aq)------------------->A+(aq) + C(s)

among A , B, C   , A having highest negative potential . highest negative potential element is on the top of the electro chemical series . so it is topmost element . top most element can displace down most element. A can replace both B and C from its salts
