Answer:
To increase surface area of the platinum electrode which results in superior quality and action of the electrodes as opposed to normal platinum electrodes.
Explanation:
Platinization of Platinum is the process of covering platinum electrode with a layer of platinum black. Platinum black is a finally divided form of platinum, optimized for catalysing the addition of hydrogen to unsaturated organic compound. This increases the surface area of the platinum electrodes and therefore exhibits action superior to that of normal electrodes.
H will definitely be positive because a bond is always more stable than no bond surely if it is a sigma bond.
For G you can't really know because you don't know how much energy is provided by the bond and if it outways the loss in disorder.
The reaction will become more spontaneous with a lower temperature because H tells you the reaction is exotherm
thanks for the answers ッ. (btw they’re on the bottom of the question if anyone doesn’t see it.
Answer:
30.6 g of C is formed.
Explanation:
2A + B → C
Average rate of reaction = 2[A]/Δt = [B]/Δt = [C]/Δt
Average rate of reaction = [C]/Δt
Average rate of reaction = 15 g / 9 min
Average rate of reaction = 1.7 g of C / min
Average rate of reaction = [C]/Δt
[C] = Average rate of reaction x Δt
[C] = 1.7 g of C / min x 18 min
[C] = 30.6 g of C
Answer:
energy is released in the reaction.
