For the reaction, A(g) + B(g) => AB(g), the rate is 0.385 mol/L.s when the initial concentrations of both A and B are 2.00 mo
Tanya [424]

Answer : The rate for a reaction will be 0.14Ms^{-1}

Explanation :

The balanced equations will be:

A(g)+B(g)\rightarrow AB(g)

In this reaction, A and B are the reactants.

The rate law expression for the reaction is:

\text{Rate}=k[A]^2[B]^1

or,

\text{Rate}=k[A]^2[B]

Now, calculating the value of 'k' by using any expression.

\text{Rate}=k[A]^2[B]

0.385=k(2.00)^2(2.00)

k=0.0481M^{-2}s^{-1}

Now we have to calculate the initial rate for a reaction that starts with 1.48 M of reagent A and 1.32 M of reagents B.

\text{Rate}=k[A]^2[B]^0[C]^1

\text{Rate}=(0.0481)\times (1.48)^2(1.32)^1

\text{Rate}=0.14Ms^{-1}

Therefore, the rate for a reaction will be 0.14Ms^{-1}

Assume we have 25 mL of a 2.5 M HCl and a solution of NaOH of unkown concentration. The two react via the following equation.
navik [9.2K]

Answer is  A - HCl is the titrant and D-NaOH is the analyte.

In a titration process, the solution of unknown concentration considered is the analyte. During titration, a standard solution(titrant) is added to an analyte until the equivalence point is achieved.

So in this case as the concentration of NaOH is not known,NaOH is the analyte.

Titrant is the solution whose concentration  is known to us and is added to an analyte until the equivalence point is reached. In this case since we know the concentration of HCl, HCl is the titrant.
