In the first 22.0 s of this reaction, the concentration of HBr dropped from 0.590 M to 0.465 M . Calculate the average rate of t

Alex

This is an incomplete question, here is a complete question.

Consider the following reaction:

$2HBr(g)\rightarrow H_2(g)+Br_2(g)$

In the first 22.0 s of this reaction, the concentration of HBr dropped from 0.590 M to 0.465 M . Calculate the average rate of the reaction in this time interval.

Answer : The average rate of reaction is, $6.25\times 10^{-3}M/s$

Explanation :

The given chemical reaction follows:

$2HBr(g)\rightarrow H_2(g)+Br_2(g)$

The average rate of the reaction for disappearance of HBr is given as:

$\text{Average rate of disappearance of HBr}=-\frac{\Delta [HBr]}{\Delta t}$

where,

$C_2$ = final concentration of HBr = 0.465 M

$C_1$ = initial concentration of HBr = 0.590 M

$\Delta t$ = change in time = 22.0 s

Putting values in above equation, we get:

$\text{Average rate of reaction}=-\frac{(0.465-0.590)M}{20.0s}\\\\\text{Average rate of reaction}=6.25\times 10^{-3}M/s$

Hence, the average rate of reaction is, $6.25\times 10^{-3}M/s$

Based on what you know about Earth's magnetic field what do you think about Mars' interior?

Tomtit [17]

The interior of mars is rigid

Explanation:

To produce the magnetic field of the earth, the outer core is fluid and constantly moving.

The outer core is made up of metals
These metals are rich in iron and nickel and some other elements.
During the early formation of the earth, these minerals differentiated into this layer of the earth based on their density.
But the outer core region is molten and fluid.
The movement of these materials is responsible for the production of the geo-magnetic field that makes the earth behave like a bar magnet.

Mars has no magnetic field and we can suggest that its interior is rigid and solid.

For the reversible reaction. A(g) = B(g). which K values would indicate that there is more B then A at equilibrium? a)K=7x10^-9.

yanalaym [24]

Answer is both (b) and (d).

<em>Explanation;</em>

Equilibrium constant is written as a ratio between concentrations of products and reactants.

The equilibrium reaction is

A(g) ⇄ B(g)

Hence, the equilibrium constant can be expressed as

K = [B(g)] / [A(g)]

If there is more B, then A should be less. Hence, K value would be more than 1.

Hence, according to the given choices, K = 4000 and K = 1 x 10⁶ can be taken as correct answers.
