What volume of chlorine gas (molar mass 71) is evolved at STP during electrolysis of fused NaCl by passage of 1 amp current for 965 second? (At STP, V = 22.4 . dm ^3 )

Step-by-step solution

2 Cl ⁻ Cl ₂+2 e ⁻ For the reaction, mole ratio = 1 2 Moles of product formed aligned & = I ( ~A ) t ( ~s ) 96500 ( C ~mol ⁻¹ ) mole ratio & = 1 965 96500 1 2 & =5 10⁻³ ~mol aligned aligned & At STP, 1 ~mol Cl _ 2( ~g ) =22.4 dm ^3 & At STP, 5 10⁻³ ~mol Cl _ 2( ~g ) =0.112 ~L aligned
