Answer:

We are giving that 12 inches make one foot and 1 inch is equivalent to 2.54 cm.

Of the given inches in centimetre will be 148. 38 cm^2.

Explanation:

Now the value that is given in inches square is 23, to calculate the value of inches given in the question into centimetre we have to multiply the value of inch with 2.54 cm.

23 \times 2.54 \times 2.54= 148.38 cm^2

Since the value is given in square hence the centimetre calculated would also be in square that is why 2.54 needs to be multiplied twice.

What is the rate law for this reaction? A + 2B → C + D
Sunny_sXe [5.5K]
Rate = k[A][B]
This means the rate is directly proportional to the concentration of A and B, i.e. first order in both.
So, if [A] doubles, and [B] stays the same, the rate will double.
If [B] doubles, and [A] stays the same, the rate will double.
If both [A] and [B] double, the rate will increase by 4 times.
You can see this mathematically from the rate law as follows:
Rate = k[2][2] = 4k and since k is constant, the rate will be 4x what it was when the [A] and [B] were each 1.

The rate law for the reaction
juin [17]

Explanation:

Since, the given reaction is as follows.

              2NO(g) + Cl_{2}(g) \rightarrow 2NOCl(g)

Hence, rate law of the reaction is as follows.

               R = k[NO][Cl_{2}]

As it is known that rate of a reaction depends on the initial concentration of products. So here, the rate of reaction will depend on the concentration of NO and Cl_{2}. Since, power of the concentrations of each of these is equal to 1. Therefore, order of the reaction is equal to 1 + 1 = 2.

According to the rate law, reactants involved in the rate determining step are NO and Cl_{2}. Hence, first step of the mechanism is the rate determining step.

Also, according to the rate of reaction doubling the concentration of NO will double the rate of reaction.

The number of reactants taking part in a single step of the reaction is known as molecularity of the reaction. Therefore, molecularity of the first step of the reaction is 2.

Both the given steps are not termolecular.
