Using the balanced equation: 2 KCIO3 -> 2 KCI + 3 O2 How many moles of

If the theoretical yield of a reaction is 0.110 g and the actual yield is 0.104 g , what is the percent yield?

Westkost [7]

Theoretical Yield is an Ideal yield with 100 % conversion of reactant to product. It is in fact a paper work.

While,

Actual Yield is the yield which is obtained experimentally. It is always less than theoretical yield because it is not possible to have 100% conversion of reactants into products. Even some amount of product is lost while handling it during the process.

Percentage Yield is Calculated as,

%age Yield = Actual Yield / Theoretical Yield × 100

Data Given:
Actual Yield = 0.104 g

Theoretical Yield = 0.110 g

Putting Values,

%age Yield = 0.104 g / 0.110 g × 100

%age Yield = 94.54 %

Consider the mechanism. step 1:step 2:overall:2a⟶bb c⟶d2a c⟶dslowfast determine the rate law for the overall reaction, where the

Ne4ueva [31]

Answer:

Rate: R = k [A]²

Explanation:

The rate law equation for a given complex chemical reaction is given as the product of molar concentrations of the reactant raised to the power their respective partial reaction orders. The sum of the partial reaction orders is equal to the overall order of reaction.

For a complex reaction, the rate law is generally determined by the slowest step, which is known as the rate-determining step.

<u>Given reaction mechanism:</u>

Step 1: 2 A⟶ B, slow step

Step 2: B+ C⟶ D, fast step

Overall: 2 A + C ⟶ D

In this given reaction mechanism, the <em>step 1 is the slow step and thus the rate determining step.</em>

Therefore, the rate law for the given mechanism is:

Rate: R = k [A]²

Here, k is the overall rate constant

Also, the overall order of the reaction = 2

Therefore, the given chemical reaction is said to be second order reaction.

Why is something that stores chemical energy?

labwork [276]

Two things that store chemical energy are coal, and wood cause when you have a fire you have to get the chemicals from somewhere to keep your fire live.

Determine the number of atoms in 5.88 moles sodium.

ozzi

1 mole ------------ 6.02x10²³ atoms
5.88 moles ---- ?

atoms = 5.88 * 6.02x10²³ / 1

= 3.539x10²⁴ atoms

Suggest an experimental method for measuring the change in concentration with time for each of the following reactions:(b) 2NO(g

USPshnik [31]

The experimental method for measuring the change in concentration with time for the given reaction is by measuring the amount of gas a reaction releases over time.

2NO(g) + Cl₂(g) → 2NOCl(g)

<h3>What is reaction rate?</h3>

The reaction rate is the rate at which a chemical reaction proceeds.
Which is proportional to both the increase in a product's concentration per unit time and the decrease in a reactant's concentration per unit time.
There is a wide range in reaction times.
The general definition is that the term "rate of a reaction" refers to the pace at which a reaction occurs.
As an illustration, iron rusting has a low reaction rate since the process is slow but wood burning has a high reaction rate because the process is quick.
