11.9 if i read your question correctly sorry if it’s wrong lol
Answer is: reaction is second order with respect to a.
This second order reaction<span> is proportional to the square of the concentration of reactant a.
</span>rate of reaction = k[a]².
k is second order rate constant and have unit M⁻¹·s⁻¹.
Integrated rate law for this reaction: <span><span>1/[a]</span>=<span>1/<span>[a]</span></span></span>₀ <span>+ kt.
t is time in seconds..</span>
Plant: leaf tissue
Human: lungs
Answer:
C) quartz
Explanation:
Quartz is a common mineral. Also, quartz isn't a metallic substance. I'm hoping that this helps :)
The rate of the reaction increases when a catalyst has been added to the reaction mixture by e) providing a new mechanism for the reaction to procced by
Catalyst, in chemistry, a substance that speeds up a reaction without itself being consumed. Enzymes are natural catalysts responsible for many important biochemical reactions.
Most solid catalysts are oxides, sulfides, halides of metals or metallic elements, and metalloid elements boron, aluminum and silicon. Gas and liquid catalysts are usually used in pure form or in combination with suitable carriers or solvents. Solid catalysts are usually dispersed in another material known as a catalyst support.
