+2081 Jmol-1
-2081 Jmol-1
-649 Jmol-1
+649 Jmol-1
Correct answer is A
∆G = ∆H - T∆S
-899 = ∆H - 2980
∆H = -899 + 2980 = + 2081 Jmol-1
How many faraday of electricity is required to produce 0.25 mole of copper?
1.00F
0.01F
0.05F
0.50F
Correct answer is D
Cu → Cu2+ + 2e
1mole Cu requires 2f
0.25 mole Cu requires x
x = 0.25x2/1 = 0.50f
32395.5
30156.3
60784.5
15196.5
Correct answer is B
Cu → Cu2++ 2e
64g Cu requires 2 x 96500 coloumbs 10g Cu requires x columbs
x = 10x2x96500/64 =30156.3
