Answer:
The half life time of first order reaction is 1.3 sec
Explanation:
Given:
First order rate constant
Initial concentration M
From the formula of first order half life time,
So half life time is given by,
sec
Therefore, the half life time of first order reaction is 1.3 sec.
Answer:
8.34
Explanation:
1) how much moles of NH₃ are in the reaction;
2) how much moles of H₂ are in the reaction;
3) the required mass of the H₂.
all the details are in the attachment; the answer is marked with red colour.
Note1: M(NH₃) - molar mass of the NH₃, constant; M(H₂) - the molar mass of the H₂, constant; ν(NH₃) - quantity of NH₃; ν(H₂) - quantity of H₂.
Note2: the suggested solution is not the shortest one.
