Answer:
E) rate of appearance of C = 0.45 M/s
rate of the reaction = 0.15 M/s
Explanation:
2A + B → 3C
Writing rate law for the reaction:
<u>Rate of reaction</u> = - = -
=
→ equation 1
Given that the rate of disappearance of A is 0.3 M/s
⇒ - = 0.3 M/s
⇒Rate of reaction = - =
×0.3 M/s
⇒<u>Rate of reaction = 0.15 M/s</u>
From equation 1, = -
=
×0.3 M/s
⇒ = 0.45 M/s
or <u>the rate of appearance of C = 0.45 M/s</u>
10 electrons will occupy the five orbitals in the atoms d sub shell like this. Each electron fills one by one in each orbital. So first 1 electron will fill the first orbital, then the second will move on to the next and so on. So for example…if there were 7 electrons, the first two sub shells would be filled, and the other three would have one electron each
