The reaction between SO2 and O2 to give SO3 was studied to determine the rate law for the reaction. The following results were o

Tom [10]

Answer : (b) The rate law expression for the reaction is:

$\text{Rate}=k[SO_2]^2[O_2]$

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

The general reaction is:

$A+B\rightarrow C+D$

The general rate law expression for the reaction is:

$\text{Rate}=k[A]^a[B]^b$

where,

a = order with respect to A

b = order with respect to B

R = rate law

k = rate constant

$[A]$ and $[B]$ = concentration of A and B reactant

Now we have to determine the rate law for the given reaction.

The balanced equations will be:

$2SO_2+O_2\rightarrow 2SO_3$

In this reaction, $SO_2$ and $O_2$ are the reactants.

The rate law expression for the reaction is:

$\text{Rate}=k[SO_2]^2[O_2]^1$

or,

$\text{Rate}=k[SO_2]^2[O_2]$

A sealed glass jar has a small amount of water on the bottom. The rest of the volume in the jar is taken up by helium gas at a p

Natalija [7]

<u>Answer:</u>

The temperature of the water is 70°C

<u>Explanation:</u>

Partial pressure of helium gas = 526 mmHg

Total pressure inside the jar= 760 mmHg

Suppose partial pressure of helium gas is $P_H_e$ and partial pressure of water is $P_H__2O$

And total pressure is $P_T$

As we know

$\mathrm{P}_{\mathrm{T}}=\mathrm{P}_{\mathrm{HE}}+\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}$

Hence

Putting the values

$760=526+\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}$

$\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}=760-526$

$\mathrm{P}_{\mathrm{H} 20}=234 \mathrm{mm} \mathrm{Hg}$

In bar,

$\mathrm{P}_{\mathrm{H} 2 \mathrm{O}}=234 \mathrm{mm} \mathrm{Hg} \times \frac{1.01325 \mathrm{bar}}{760 \mathrm{mm} \mathrm{Hg}}$

= 0.312 bar

Now according to the steam table

With the vapour pressure of water as 0.312 bar the temperature corresponds to 70°C
