Reaction Rates
inn [45]

Answer:

PART A 1st order in A and 0th order in B

Part B The reaction rate increases

Explanation:

<u>PART A </u>

The rate law of the arbitrary chemical reaction is given by

-r_A=k\times\left[A\right]^\alpha\times\left[B\right]^\beta\bigm

Replacing for the data

Expression 1 0.00639=k\times{0.12}^\alpha\times{0.22}^\beta

Expression 2 0.01280=k\times{0.24}^\alpha\times{0.22}^\beta

Expression 3 0.00639=k\times{0.12}^\alpha\times{0.11}^\beta

Making the quotient between the fist two expressions

\frac{0.00639}{0.01280}=\left(\frac{0.12}{0.24}\right)^\alpha

Then the expression for \alpha

\alpha=\frac{ln\frac{0.00639}{0.01280}}{ln\frac{0.12}{0.24}}=1\bigm

Doing the same between the expressions 1 and 3  

\frac{0.00639}{0.00639}=\left(\frac{0.22}{0.11}\right)^\beta

Then

\beta=\frac{ln\frac{0.00639}{0.00639}}{ln\frac{0.22}{0.11}}=0\bigm

This means that the reaction is 1st order respect to A and 0th order respect to B .

<u>PART B </u>

By the molecular kinetics theory, if an increment in the temperature occurs, the molecules will have greater kinetic energy and, consequently, will move faster. Thus, the possibility of colliding with another molecule increases. These collisions are necessary for the reaction. Therefore, an increase in temperature necessarily produces an increase in the reaction rate.

Which technology is NASA developing that will help astronauts reach Mars? Corona Freedom Orion Skylab
stiv31 [10]

Answer:

The answer is "Orion technology"

Explanation:

NASA tested that perhaps the abort system on the Biomechanical properties fires faster than that of the rocket, possibly costing colonists during launch or a crisis. It test is a significant step forward in Agency's plans again for the Artemis space mission, which will pave the way for human missions to The moon. NASA is building a humanoid spacecraft for long-range space missions for the first time in generations.  As just a result, they are beginning a new age of space travel. Orion would be used to transport the crew into space as a surveillance vehicle. Also, it helps astronauts to flights and ensures a safe return to orbit in the case of an emergency release.
