Wavelength x Frequency = Speed
So, 5.9 x 10^-7 x F = 3 x 10^8
Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz

Hey there!
Given the reaction:
B + H⁺ => HB⁺
At half-equivalence point : [B] = [HB⁺]
=> [B] / [HB⁺] = 1
Henderson-Hasselbalch equation :
pH = pKa + log ( [B] ) / ( HB⁺)]
pH = 14 - pKb + log ( 1 )
pH = 14 - 7.95 + 0
pH = 6.05
Answer C
Hope that helps!
Answer:
The correct answer is reaction will achieve equilibrium by forming more products and will move in left to right direction.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
- If Q >
, then the equilibrium will shift in left direction or in backward direction.the reaction will move back to the formation of reactants from the product - If Q <
, then the equilibrium will shift in right direction or in forward direction.The reaction will form more products
I believe it's D. A catalyst causes an increases the rate of a reaction without itself being consumed.
