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
Correct answer choice is :
D) By subtracting the pOH from 14
Explanation:
P is usually done with very small or very large values. To determine the pH of an aqueous liquid you want to know the density of the hydronium ion in moles per liter. The pH is then determined using the expression pH = - log [H3O+].POH is the contrary of the logarithm of the OH- ion concentration. pOH = - log [OH-] pH + pOH = 14, for an aqueous liquid at 25C, despite how many acid or base has been added to the suspension.

Everything haplens due to a necessity hence u need to know the need.next u definitely need a plan, then do the work,evaluating and rediesigning is necessary to give it a final look and at last obviously test the results
Answer: The concentration of the KOH solution is 1.01 M
Explanation:
According to neutralization law:
where,
= basicity of = 1
= acidity of KOH = 1
= concentration of HCl = 3.00 M
= concentration of KOH = ?
= volume of HCl = 35.3 ml
= volume of KOH = 105.0 ml
Putting the values we get:
Thus the concentration of the KOH solution is 1.01 M
