Answer:
what is the pOH of a with a pH of 10 14
<span>Make an experiment with pH and Temperature the different variables. Test each one individually and see what factors increase reactivity of the enzyme. Once you figure out the best scenario for each variable. Attempt both variables simultaneously to be sure that the variables do not counteract with each other.</span>
<span>The lattice structure in a metal is weaker than the lattice structure of an ionic compound. This is because the metals have free electrons which can freely move around while ionic compounds are strongly bonded. Hope this answers the question.</span>
Answer:
a. 0.933 M⁻¹.cm⁻¹
b. 0.003 M/s
Explanation:
a. The molar absorptivity coefficient (ε) is the ability of 1 mol of the substance to mitigate the light of a wavelength. It means that it's a measure of how strong a substance can absorb radiation. It can be calculated by the absorbance (A), the concentration (c) and the length of the cuvette (l).
ε = A/(c*l)
Thus, at t = 0, for the blue reactant, A = 0.77, c = 0.75 M, l = 1.10 cm.
ε = 0.77/(0.75*1.10)
ε = 0.933 M⁻¹.cm⁻¹
b) The rate of the reaction can be found by the rate of desapering of the blue reactant. Let's find the concnetration when t = 30.00 s:
ε = A/(c*l)
0.933 = 0.67/(c*1.10)
1.10c = 0.67/0.933
1.10c = 0.7181
c = 0.65 M
Thus, the rate is the variation of the concentration divided by the time variation:
r = (0.75 - 0.65)/30
r = 0.003 M/s
Because the coefficient of the blue reactant is 1, the rate of reaction is equal to the rate of disappearing of B, 0.003 M/s.
