bulgar [2K]

Answer:

Few important points related to S_N2 reaction:

1. S_N2 is a one-step reaction that follows second order kinetics.

2. In S_N2 reaction, a transition state is formed in situ.

3. Strong nucleophiles like OH^- \ or\  CN^- are used in case of bi-molecular nucleophilic substitution reaction.

Ethyl acetate can be prepared by a second-order nucleophilic substitution reaction between acetic acid and ethyl bromide.  

The reaction between acetic acid and ethyl bromide is drawn below:

The value of Δ G ° ' for the conversion of 3-phosphoglycerate to 2-phosphoglycerate (2PG) is + 4.40 kJ/mol . If the concentratio
Mrac [35]

Answer:The concentration of 2-phosphoglycerate is 0.415 mM

Explanation:

3-phosphoglycerate\rightleftharpoons 2-phosphoglycerate

Relation between standard Gibbs free energy and equilibrium constant follows:

\Delta G^o=-RT\ln K

where,

\Delta G^o = Standard Gibbs free energy = +4.40  kJ/mol = 4400 J/mol  (Conversion factor: 1kJ = 1000J)

R = Gas constant = 8.314J/K mol

T = temperature = 25^0C=(25+273)K=298 K

Putting values in above equation, we get:

4400J/mol=-(8.314J/Kmol)\times 298K\times \ln K

\ln K=-1.776

K=0.169

K=\frac{ 2-phosphoglycerate}{3-phosphoglycerate}

0.169=\frac{ 2-phosphoglycerate}{2.45mM}

2-phosphoglycerate}=0.415mM

Thus the concentration of 2-phosphoglycerate is 0.415 mM

Can matter every be destroyed? Why or why not?
REY [17]

Hey

Matter can neither be created nor destroyed.

Explanation:

This is the law of conservation of matter (mass). One can prove this by performing a simple experiment at home.

Have a great day
