Answer:
Chromium is reduced in forward reaction
Explanation:
A species is said to be oxidized if oxidation number of the species increases.
A species is said to be reduced if oxidation number of the species decreases.
Oxidation number of Cr in = +6
Oxidation number of Cr in = +3
So change in oxidation number of Cr in forward reaction = (+3)-(+6) = -3
Hence oxidation number of Cr decreases on going from to .
So, chromium is reduced in forward reaction.
Answer:
The main products are ATP, carbon dioxide, and water.
Osmosis is the movement of water from high concentration to low concentration while diffusion is the net of movement of gases from high concentration to low concentration
Answer:
c. −1.22 × 10^4 K
Explanation:
Generally, the slope of an Arrhenius plot can be determined either from the graph of In k against 1/T or the available experimental data of the rate constant (k) and the absolute temperature. Mathematically,
Where:
L/(mol.s)
L/(mol.s)
K
K
slope = (ln 2.9*10^-1 - ln 6.6*10^-4)/(1/500 - 1/400)
slope = (-1.238+7.323)/(0.002-0.0025)
slope = 6.085/-0.0005 = -1.22*10^4 K
