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
<span>Non-stoichiometric defects are </span>compounds which contain the combining elements in a ratio different from that required by their stoichiometric formula. The solids with metal excess <span>defect </span>contain metal in excess to the stoichiometric ratio. Such defect is caused due to either of the following reasons:
1. <span>Metal excess Defect due to Anionic Vacancies:
In this, </span>negative ions may be missing from their lattice sites leaving holes in
which the electrons remain entrapped to maintain the electrical
neutrality.
2. Metal excess defect due to the presence of extra cations at interstitial sites:
In this case, there are extra positive ions occupying interstitial
sites and the electrons in another interstitial sites to maintain
electrical neutrality. The defect may be visualized as the loss of
non-metal atoms which leave their electrons behind. The excess metal
ions occupy interstitial positions.
Answer:
Gamma
Explanation:
This is because the prticles that are shown can be found in many gamma cancers which mean that that is from gamma
