I believe the correct answer from the choices listed above is option 2. From the balanced equation, the energy is absorbed as the bonds are broken. Energy is needed to be supplied for the bonds to be broken.
Hope this answers the question. Have a nice day.
Answer:
Explanation:
1. the 1/2 reaction that occurs at the cathode
3Cl2(g) +6e^- -------------> 6Cl^- (aq)
2 the 1/2 reaction that occurs at the anode
2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-
2MnO2(s) + 8OH^-(aq) ----------> 2MnO4^- (aq) + 4H2O(l) +6e^-
E0 = -0.59v
3Cl2(g) +6e^- -------------> 6Cl^- (aq)
E0 = 1.39v
3Cl2 (g) + 2MnO2 (s) + 8OH^(−) (aq)---------> 6Cl^(−) (aq) + 2MnO4^(−) (aq) + 4H2O (l)
E0cell = 0.80v
Answer:
When the temperature of an object increase, the object's particle move faster.
Explanation:
Energy in form of the heat can be absorbed by the object, energy is translated to object's particles. In that moment, energy is transformed in another form - kinetic energy. Kinetic energy manifest as a faster particle movement ( or vibration ).
Answer: Δn for the following equation in relating Kc to Kp is 2.
Explanation:
The balanced chemical equation is:
Relation of 
with 
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles = 
Putting values in above equation, we get:
Thus the value of Δn for the following equation in relating Kc to Kp is 2.
