Hope it helps you!
<span>Answer: 5.32 x 10⁻³ M
Explanation:
1) The rate law for a first order reaction is:
</span><span />
<span>r = - d [A] / dt = k[A]
</span><span />
<span>2) When you integrate you get:
</span><span />
<span> [ A] = Ao x e ^(-kt)
</span><span />
Remember that here A is PH₃
<span>3) Plug in the data: Ao = 0.0316M, k = 0.0180 /s, and t = 99s
</span><span />
<span>[PH₃] = 0.0316 M x e ^( - 0.0180/s x 99s) = 5.32 x 10⁻³ M</span>
Answer:
Δx(m.Δv)=h/4π
here ,
Δv = uncertainty in velocity
10−11×10−27×Δv=6.626×10−34/4×22/7
=5.25×103ms−1
Hey there!:
It is a solid at room temperature.
Take a look at the structure of the compound. It has 3 rings total, two of which are phenyl rings, 3 methyl groups and a pentyl group while there is only one OH. That is a lot of non-polar groups for just one polar group. This is why it is sparingly soluble in MeOH at RT, it really is not a very polar molecule (the general rule of thumb is 5 C's for every polar group for the molecular to be considered polar, this of course is a generalization).
I hope that helps.
