What is the value of E_{cell} ? Cr | Cr^{3+} (0.1 M) || Fe^{2+} (0.01 M) | Fe Given , E^\circ_{Cr^{3+}\/Cr} = -.74 V and E^\circ_{Fe^{2+}\/Fe} = -0.44 V

JEE Advanced Model Paper 3 with solutions for online practice

Paragraph - I :

Cells are two types: (a) Electrolytic cell which converts electrical energy into chemical energy and (b) Electrochemical cell which convert is chemical energyinto electrical energy.
In Electrochemical cells if Ecell is zero then cell is in equilibrium, if Ecell ispositive cell is spontaneous.
