At a certain temperature this reaction follows first-order kinetics with a rate constant of 0.184 s^-1 ? Suppose a vessel contai
meriva

Answer:

0.57 M

Explanation:

rate = change in concentration /time

Initial concentration of Cl2O5 = 1.16 M

Let the concentration of Cl2O5 after 5.70 seconds be y

rate = (1.16 - y)/5.7

The reaction follows a first order

Therefore, rate = ky = 0.184y

0.184y = (1.16 - y)/5.7

0.184y × 5.7 = 1.16 - y

1.0488y + y = 1.16

2.0488y = 1.16

y = 1.16/2.0488 = 0.57 M

Concentration of Cl2O5 after 5.70 seconds is 0.57 M

Acetonitrile major species present when dissolved in water
IrinaVladis [17]

Acetonitrile refers to the chemical compound exhibiting the formula CH₃CN. It is the basic organic nitrile and a colorless liquid. It is generated primarily as a byproduct of acrylonitrile production. It is used as a polar aprotic solvent in the purification of butadiene and in organic synthesis.  

The addition of water to cyanides generates amines and acids. Acetonitrile produces ammonia and acetic acid.  

CH₃CN (acetonitrile) → CH₃COOH (acetic acid) + NH₃ (ammonia)
