What is the overall reaction order for this rate law: rate = k[A]2[B][C]?
dybincka [34]

Zero order are reactions in which concentration of reactant has NO effect on RATE OF REACTION.


2. First order are reactions in which concentration of one reactant is proportionate to the RATE OF REACTION.

Exp: That means when you increase the concentration of the one reactant, then the rate of reaction will increase by the same degree of extent.


3. Second order are reactions in which concentration of two reactant has an effect on the RATE OF REACTION.


Formula:

1. Zero order Rate = k

2. First order Rate = k(A)^m

3. Second order Rate = k(A)^m(B)^n


where () represents concentration

and equation is mA + nB -> Product.

What is the molality of a solution that is obtained by dissolving 2.922 g of NaCl into 1000.0 g of water if the molar mass of Na
never [62]
In order to find molarity, you must first find the number of moles that was dissolved.

Now, Moles = Mass ÷ Molar Mass
                   
⇒  Moles of NaCl  = 2.922 g ÷ 58.44 g/mol 
                       
                               = 0.05 moles

∴ the Molarity of the NaCl is 0.05 M [Option 1]

What is the [H ] of a solution of 0.001 M aqueous sulfuric acid (H2SO4) is H2SO4 ionizes in water according to the balanced chem
Ainat [17]

Answer:  0.002 M

Explanation:

The balanced chemical equation for ionization of H_2SO_4 in water is:

H_2SO_4\rightarrow 2H^++SO_4^{2-}

According to stoichiometry :

1 mole of H_2SO_4 ionizes to give =2 mole of H^+ ions

0.001 mole of H_2SO_4 ionizes to give = \frac{2}{1}\times 0.001=0.002 mole of H^+ ions

Thus H^+ of a solution of 0.001 M aqueous sulfuric acid is 0.002 M
