How many moles of oxygen are produced when 29.2 g of water is decomposed according to H20 H2 + O2​
Katarina [22]

8.1moles

Explanation:

Given parameters:

Mass of water to be decomposed = 29.2g

Unknown:

Number of moles of oxygen.

Solution:

To solve this problem, we first write the balanced reaction equation :

               2H₂O    →     2H₂    +    O₂

Now convert the given mass of the water to number of moles;

  Number of moles of water = \frac{mass}{molar mass}

 

  Molar mass of water = 2(1) + 16 = 18g/mol

  Number of moles of water = \frac{29.2}{18}  = 16.2moles

   From the balanced reaction equation:

   2 moles of water produced 1 mole of oxygen gas;

   16.2 mole of water will produce   \frac{16.2}{2}  = 8.1moles of oxygen gas

A first order reaction has a rate constant of 0. 543 at 25°C. Given that the activation energy is 75. 9 kj/mol. Calculate the ra
Rasek [7]

The rate constant of first order reaction at 32. 3 °C is 0.343 /s must be less the 0. 543 at 25°C.

First-order reactions are very commonplace. we have already encountered  examples of first-order reactions: the hydrolysis of aspirin and the reaction of t-butyl bromide with water to present t-butanol. every other reaction that famous obvious first-order kinetics is the hydrolysis of the anticancer drug cisplatin.

The value of ok suggests the equilibrium ratio of products to reactants. In an equilibrium combination both reactants and merchandise co-exist. big ok > 1 merchandise are k = 1 neither reactants nor products are desired.

Rate constant K₁  = 0. 543 /s

T₁  = 25°C

Activation energy Eₐ =  75. 9 k j/mol.

T₂ = 32. 3 °C.

K₂ =?

formula;

log K₂/K₁=  Eₐ /2.303 R [1/T₁ - 1/T₂]

putting the value in the equation  

K₂ = 0.343 /s

Hence, The rate constant of first order reaction at 32. 3 °C is 0.343 /s

The specific rate steady is the proportionality consistent touching on the fee of the reaction to the concentrations of reactants. The fee law and the specific charge consistent for any chemical reaction should be determined experimentally. The cost of the charge steady is temperature established.
