Im answering question 2
Because it increases the kinetic energy of reactants and so the frequency of collision between reactants. Thus, provided the temperature is not too high to lead to denaturation of reactants, increase in temperature increases the rate of reaction

And for ques. 7:
It gets affected when gaseous reactants in which products formed have less volume than reactants, so increase in pressure increases the rate of reaction

Adding an inhibitor to a chemical reaction will have which of the following effects on a reaction?
Levart [38]

Answer: a. the inhibitor will decrease the rate of reaction.

Explanation: The rate of the reaction is affected by addition of inhibitors which are also called as negative catalysts as they decrease the rate of reaction unlike catalysts which enhance the rate of reaction.

Inhibitors delay, slow or prevent the chemical reactions by binding with the substrate or the catalyst and hence prevent them to function normally.

Suppose that the saturation magnetization Mmax of the ferromagnetic metal nickel is 4.41 × 105 A/m. Calculate the magnetic momen
Lady bird [3.3K]

Answer : The magnetic moment of a single nickel atom is 4.82\times 10^{-24}Am^2

Explanation :

Formula used :

M_{max}=(\frac{N}{V})\times \mu

where,

M_{max} = saturation magnetization = 4.41\times 10^5A/m

N = Avogadro's number = 6.022\times 10^{23}atoms/mol

V = volume of nickel atom

\mu = magnetic moment

First we have to calculate the volume of nickel atom.

Density=\frac{Mass}{Volume}

8.90g/cm^3=\frac{58.71g/mol}{Volume}

Volume=\frac{58.71g}{8.90g/cm^3}

Volume=6.59cm^3=6.59\times (100)^3m^3

Now we have to calculate the magnetic moment of a single nickel atom.

M_{max}=(\frac{N}{V})\times \mu

4.41\times 10^5=(\frac{(6.022\times 10^{23})}{6.59})\times (100^3)\times \mu

\mu=4.82\times 10^{-24}Am^2

Therefore, the magnetic moment of a single nickel atom is 4.82\times 10^{-24}Am^2
