Chemical equilibrium is reach when the concentrations of the product and reactants will no longer change with time. this does not mean that there is no change in concentration, only the net change is zero. the forward rate of reaction is now equal to backward rate of reaction.

The rate law of the reaction NH3 + HOCl → NH2Cl + H2O is rate = k[NH3][HOCl] with k = 5.1 × 106 L/mol·s at 25°C. The reaction is
SIZIF [17.4K]

Answer:

40% of the ammonia will take 4.97x10^-5 s to react.

Explanation:

The rate is equal to:

R = k*[NH3]*[HOCl] = 5.1x10^6 * [NH3] * 2x10^-3 = 10200 s^-1 * [NH3]

R = k´ * [NH3]

k´ = 10200 s^-1

Because k´ is the psuedo first-order rate constant, we have the following:

b/(b-x) = 100/(100-40) ; 40% ammonia reacts

b/(b-x) = 1.67

log(b/(b-x)) = log(1.67)

log(b/(b-x)) = 0.22

the time will equal to:

t = (2.303/k) * log(b/(b-x)) = (2.303/10200) * (0.22) = 4.97x10^-5 s

determine the number of possible product for treating the following compound with NBS adligh(Hv). Countsterioisomers as a single
lord [1]

Two distinct products of the reaction could emerge, both of which might turn out to be stereoisomers of one another.

<h3>What is the number of products?</h3>

We now understand that the chemical as demonstrated can experience monobromination, and the resulting compound is the same compound. However, due to the reaction's nature, we would have two steroisomers.

Given the reaction's process, we are aware that there are two distinct reaction products that may turn out to be stereoisomers of one another.

3Fe+4H2O--&gt;Fe3O4+4H2 What is the mole ratioof Fe3O4 to Fe?
love history [14]
For every 3 Fe there is only 1 Fe3O4 producing.
So, ratio would be: Fe3O4 / Fe = 1 / 3

In short, Your Answer would be: 1 : 3

Hope this helps!
