Answer:
r = 0.0018 molxL⁻¹xs⁻¹
t = 472.22 s
Explanation:
The rate of the reaction is given by:
Where <em>r</em> is the rate, <em>k</em> is the rate constant, <em>[A]</em> is the initial concentration of the reactant and <em>n</em> is the order of the reaction. So, for this problem:
r = 0.0018x[1.70]⁰
r = 0.0018 molxL⁻¹xs⁻¹
The rate is also the variation of the concentration divided by the time. So, for the half-life, the concentration will be decreased by half and will be 0.85 mol/L. So the variation will be 1.70 - 0.85 = 0.85 mol/L. So:
0.0018 = 0.85/t
t = 0.85/0.0018
t = 472.22 s
m/sec is the unit of velocity.
Explanation:
The displacement is a vector quantity. It is a measure difference between the end and start point of a moving object.
The displacement of an object is measured in metres, kilometers, centimeter or inches. But the SI unit of displacement is always converted to metres.
The time may be in minutes, hours or second, but the SI unit of time is sec
velocity with respect to displacement is defined as rate at which displacement changes with time.
from the formula :
velocity=diplscement/time
= m/sec
So the SI unit of velocity is m sec
Answer: X + e going left towards + energy
Explanation: divide all sides
<span>the point at which the concentrations of reactants and products do not change with time. It appears as though the reaction has stopped but in fact the rates of the forward and reverse reactions are equal so reactants and products are being created at the same rate..</span>
