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

This is ur answer....
<em>Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Starch is stored in seeds and other plant parts as a food source.</em>
