Answer:

Use this: I think the photochemical smog levels are higher during the summer do to the increase in car usage and pollution. Studies show that more people use cars in the summer. In addition, the hot, musty, humid air in the summer can significantly increase pollution effect.

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.

Describe the three steps of solution formation. be sure to include the details regarding the dissolving of the substance
Elza [17]

The three steps involve;

Step 1: Separation/expansion of the solute particles

Step 2: Separation/expansion of the solvent particles

Step 3; Combining the solute and solvent particles


The first two steps are usually endothermic. Step 3, nonetheless, can be either exothermic or endothermic and is significant in determining whether the dissolving process will be endothermic or exothermic.

If an element has 3 valance electrons what row is it in?
klemol [59]

It can be any row

Explanation:

An element with a valence electrons of 3 can be in any row on the periodic table.

The rows are the horizontal arrangement of elements on the periodic table.

Elements on the same row have the same energy level.

  • The periodic table rows are called periods.
  • It is only in the groups that we can find such element.
  • Group 3 elements have 3 valence electrons.
  • Since this group cuts through all the rows, therefore, elements with 3 valence electrons can be found in any row.
