You have to decide to change the temperature at which you run a certain reaction in hope of obtaining more product more quickly.
Alexandra [31]

Answer:

see explanation

Explanation:

The reaction has a negative rate law; i.e., Rate = - ΔConcentration / ΔTime which is graphically a negative slope for the plot of Rate as a function of reactant concentration. => Rate ∝ f(Reactant Concentration). However, by raising the temperature, an increase the probability of reaction occurs and the formation of more product.

True [87]

Answer:

Lionfish are native to the Indo-Pacific region. However, a hurricane caused six fish from an aquarium to accidentally be swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to rapidly increase in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of ocean. These fish have predators such as sharks and scorpion fish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food. Their one predator is humans, who have recently started fishing them for food. In the Atlantic Ocean, algae and seaweed are producers. Small fish, crabs, and other crustaceans make up the first and secondary consumers. Sharks and orcas are some of the larger predators, which are also consumers. Bacteria and fungi are the decomposers that break down food. Lionfish are consumers because they eat fish and small crustaceans.

A series of experiments investigating the reaction of (CH3)3CCl with H2O to create (CH3)3OH produces a plot of Ln[(CH3)3CCl] vs.
Helga [31]

Explanation:

There will occur a straight line for the curve of Ln[(CH_{3})_{3}CCl] Vs. time. Since, it is a first order reaction therefore, the formula of its half-life will be as follows.

         Half-life = \frac{ln 2}{k}

or,         k = \frac{ln 2}{t_{\frac{1}{2}}}

               = \frac{ln 2}{220} sec^{-1}

So, rate of the reaction will be as follows.

          Rate = [(CH_{3})_{3}CCl]^{1}

                   = \frac{ln 2}{220} sec^{-1} \times 0.15 M

                   = 0.000473 Ms^{-1}

                   = 4.73 \times 10^{-4} Ms^{-1}

Thus, we can conclude that the instantaneous rate of given reaction is  4.73 \times 10^{-4} Ms^{-1}.

Why is there so little evidence of the Period of Heavy Bombardment on Earth?
OverLord2011 [107]

C. Weathering, plate movements and volcanoes destroyed many of

the craters

Explanation:

The earth is a dynamic planet. Both external and internal processes sculpt and shapes the surface and interior of the earth primarily from the energy from the sun and the primordial heat accumulated during the formation of the earth.

  • The period of heavy bombardment of the earth resulted in the creation of craters and other impact features on the earth surface.
  • As earth evolved, the process of weathering which is one of the tools of denudation caused the lowering and changing of the earth. Through this process sedimentary rocks were formed.
  • The movement of the earth through plate tectonics also greatly shaped the earth. New materials from the interior were brought to the surface. Some existing parts were destroyed at subduction zones. Some also became elevated.
  • Volcanism also brought new materials to the surface and this changed the terrain.
