Why acetyl salicylic acid doesnot give positive result with ferric chloride?

How do isomers presence influence the industrial process? Their diffrences in properties that they might have and the possible consequence of ignoring the presence of isomerism?

In the following problems, there are a number of strategies that could be used to solve for x.  Work through each problem until you can decide which strategy to use and explain any assumptions you could make to solve the problem more easily.

iii)  Consider the following            

0.250 moles of CO2 were placed in a 1L closed container at 20000C, 

CO2(g)         ⇌       2CO  +  O2(g)        K=6.40x10-7

iv)    H2 and I2 are placed in a closed container at 4400C, to form HI(g).  If K=49.7, 

4.00 mol of H2(g) and 2.00 mol I2(g) are placed in a 2.00 L container. 

H2(g)    +     I2(g)    ⇌     2HI(g)

In the following problems, there are a number of strategies that could be used to solve for x.  Work through each problem until you can decide which strategy to use and explain any assumptions you could make to solve the problem more easily.

i)  I2(g) and Br2(g) react in a 2.0L closed container at 1500C to produce IBr as shown below:

          K= 1.2x102 and the container initially contained 4.00 mol of I2 and 4.00 mol of Br2, 

I2(g)   +   Br2(g)      ⇌       2IBr(g)

ii) Consider:

If K= 1.60 x10-5,   0.80 mol NOCl is placed in a 2.00L container at 350C. 

2NOCl(g)     ⇌       2NO(g)  +  Cl2(g)

 If 0.500 mol of iodine and 0.500 mol of chlorine are initially placed into a 2.00-L reaction vessel at 25°C, find the concentrations of all entities at equilibrium.

I2(g)     +     Cl2(g)    ⇌    2 ICl(g)          K = 81.9 at 25°C

According to the following equation, calculate the equilibrium constant (at 3270C) if the concentrations at equilibrium given below were used.

[CO(g)] = 0.079 mol/L

[H2(g)] = 0.158 mol/L

[CH3OH(g)] = 0.021 mol/L

CO(g)  + 2 H2(g)   ⇌  CH3OH(g)
