What data should be plotted to show that experimental concentration data fits a first-order reaction? A) 1/[reactant] vs. time B
natita [175]

Answer:

C) In[reactant] vs. time

Explanation:

For a first order reaction the integrated rate law equation is:

A = A_{0}e^{-kt}

where A(0) = initial concentration of the reactant

A = concentration after time 't'

k = rate constant

Taking ln on both sides gives:

ln[A] = ln[A]_{0}-kt

Therefore a plot of ln[A] vs t should give a straight line with a slope = -k

Hence, ln[reactant] vs time should be plotted for a first order reaction.

Explanation:

Given: \lambda = 8.38\:\text{nm} = 8.38×10^{-9}\:\text{m}

Its frequency \nu is defined as

\nu = \dfrac{c}{\lambda} = \dfrac{3×10^8\:\text{m/s}}{8.38×10^{-9}\:\text{m}}

The radius of a strontium atom is 215 pm. How many strontium atoms would have to be laid side by side to span a distance of 4.19
Solnce55 [7]

Answer:

0.97 ×  10⁹ strontium atoms

Explanation:

if       1 pm is equal with 10⁻⁹ mm

then  215 pm are equal to X mm

X = (215 ×  10⁻⁹) / 1 = 215 ×  10⁻⁹ mm

Now the diameter of the strontium atom is twice the radius:

diameter = 215 ×  10⁻⁹ × 2 = 430 ×  10⁻⁹ mm

if           1 strontium atom have a diameter of 430 ×  10⁻⁹ mm

then      X strontium atom are needed to be laid said by side to span a distance of 419 mm

X = (419 × 1) / (430 ×  10⁻⁹) mm = 0.97 ×  10⁹ strontium atoms
