(6.4) The rate of a chemical reaction increases with an increase in the concentration of one or more reactants. This is best explained by which statement? Select one: a. The higher concentration of reactants increases the activation energy of the reaction. Ob. The higher concentration of reactants increases the potential energy of the molecules. c. The higher concentration of reactants increases the frequency of collisions between molecules. d. The higher concentration of reactants increases the temperature of the molecules. Check...
ane Transport - Facilitated Diffusion Side with higher concentration of molecules Transport protein Plasma membrane Facilitated diffusion causes a net movement of molecules down their concentration gradient. mework : Membrane Transport - Active Transport Side with higher concentration of square molecules Transport protein Energy input from the cell Plasma membrane Side with lower concentration of square molecules
If acetic acid has a concentration of 205 t it was mixed wla solution f sodium acetate at a concentration of . 15M, what would the PH be if the ka=18E-5 2. If an ammonium solution had a concentration of .45, and it was mixed w/ an ammonium Chloride solution of .29, what would the pH be if the kb = 1. 865
Ture of false 4. The higher the frequency, the lower the reactance of a capacitor (T ot F) 5. The lower the frequency, the higher the reactance of an inductor (T ot F) 8. The average value of a sinusoidal waveform over one full cycle is 2Am, where Am is maximum amplitude of waveform. (T ot F) 9. For a purely reactive load (inductive or capacitive) the power factor FP =1. (T ot F) 10. If the current leads the...
