In a mixture of gases, the total pressure is equivalent to the aggregate of all the partial pressures of the single element of the gas.
It can be written as = P₁ + P₂ + P₃ and so on.
The partial pressure will be:
Option A. 0. 31 atm
Pressure can be estimated by:
<u>PV = nRT</u>
Where,
And,
Solving finally we get,
Therefore, 0.31 atm is the partial pressure of the hydrogen gas.

Answer :
The rate law expression for zero order reaction will be:
The rate law expression for first order reaction will be:
The rate law expression for second order reaction will be:
Zero order reaction : There is no affect on the rate law.
First order reaction : The rate law becomes doubled.
Second order reaction : The rate law becomes quadrupled.
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 given reaction is:
The rate law expression for zero order reaction will be:
The rate law expression for first order reaction will be:
The rate law expression for second order reaction will be:
Now we have to determine that if doubling of the concentration of A then the rate of reaction will be:
As we know that the zero order reaction does not depend on the concentration of reactant. So, there is no affect on the rate law.
As we know that the first order reaction depend on the concentration of reactant. So, the rate law becomes doubled.
As we know that the second order reaction depend on the concentration of reactant. So, the rate law becomes quadrupled.
Answer:
pH = -1
Explanation:
A solution of 10 mol·L⁻¹ HCl is very acidic.
HCl is a strong acid, so it dissociates completely in water and
To get the pH, you take the negative logarithm of the hydronium ion concentration.
So, a pH = -1 represents a very acidic solution.
