The graph above shows the progress of a chemical reaction. Based on the graph, which of the following is true?
2 answers:
Answer: b. Reaction A is not enzyme-catalyzed, while reaction B is enzyme-catalyzed
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products. It is the difference between the energy of activated complex and energy of reactants.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.

From 15 mol of Silver nitrate, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.
The balanced chemical reaction for the synthesis of silver chloride has been:
From the balanced equation, since there has presence equal moles of silver nitrate and sodium chloride, the moles of silver chloride formed has been equivalent. Thus, 1 mole of silver nitrate gives 1 mole of silver chloride.
The moles of silver nitrate available are,
The moles of silver nitrate produced can be given as:
Thus, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

Answer:
Wavelength,
Explanation:
We have,
Velocity of the object,
Mass of the object,
It is required to find the wavelength of the object. The relation between wavelength and velocity of the object is given by :
h is Planck's constant
So, the wavelength of the object is .
