Answer:
ΔG = -105.4 kJ/mol
The system is spontaneous as written.
Explanation:
Step 1: Determine Gibbs free energy of reaction (ΔG)
We use the following expression.
ΔG = ΔH - T × ΔS
where,
ΔG = ΔH - T × ΔS
ΔG = 120.5 kJ/mol - 298 K × 0.7582 kJ/mol.K
ΔG = -105.4 kJ/mol
Step 2: Determine the spontaneity of the system.
Since ΔG < 0, the system is spontaneous as written.
Answer:it reacts chemically to produce heat and gas with rapid expansion of matter. It is a rapid chemical reaction
Explanation:
Answer:
pH = 4
Explanation:
pH is a base 10 logarithmic scale
1000 = 10^3
7 -3 = pH = 4
Solution :
Cd(s) ----------------------> 
(aq) + 2
, 
= 0.34 v
(aq) + 2 ------------> Cu (s) , = -0.04 v
----------------------------------------------------------------------------------------------
Cd(s) + (aq) -------------> (aq) + Cu (s) , = 0.30 v
The cell potential is defined as the measure of 
between the 
of an electrochemical cell.
