Cell is represented as Anodic compartment ∣∣ Cathodic compartment
Thus, in \(A∣A^+∣∣B^+∣B\)
At the anode (left side): \(A → A^+ + e^-\)
At the cathode (right side): \(B^+ + e^- → B\)
The overall cell reaction is:
\(A + B^+ → A^+ + B\)
This represents the process occurring in the electrochemical cell, where A is oxidized at the anode to form A+ and B+ is reduced at the cathode to form B.
So, the correct option is (D): \(A + B^+ → A^+ + B\)
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
Predict the major product $ P $ in the following sequence of reactions:
(i) HBr, benzoyl peroxide
(ii) KCN
(iii) Na(Hg), $C_{2}H_{5}OH$
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
An electrochemical cell is a device that is used to create electrical energy through the chemical reactions which are involved in it. The electrical energy supplied to electrochemical cells is used to smooth the chemical reactions. In the electrochemical cell, the involved devices have the ability to convert the chemical energy to electrical energy or vice-versa.
