Answer:
The concentration of that should used originally is
Explanation:
From the question we are told that
The necessary elementary step is
The time taken for sixth of 0.5 M of reactant to react
The time available is
The desired concentration to remain
Let Z be the reactant , Y be the first product and X the second product
Generally the elementary rate law is mathematically as
Where k is the rate constant , is the concentration of Z
From the elementary rate law we see that the reaction is second order (This because the concentration of the reactant is raised to power 2 )
For second order reaction
Where is the initial concentration of Z which a value of
From the question we are told that it take 9 hours for the concentration of the reactant to become
So
=>
For
Answer:
Explanation:
The hydrostatic pressure is defined as the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity, the formula is:
P = ρgh + P₀
Where:
ρ is density (1020kg/m³)
g is gravity (9,8m/s²)
h is depth (150m)
P₀ is the atmspheric pressure (101325 Pa)
Replacing, P = 1'600'725 Pa
