Shalnov [3]2 years ago

Answer: false .

Explanation: Weight is the measure of the force of gravity on an object. The mass of an object will never change, but the weight of an item can change based on its location.

For example, you may weigh 100 pounds on Earth, but in outer space you would be weightless.Mass never changes. Weight, which is a product of mass times gravity, may change due to a difference in gravity

Answer:

\huge\boxed{\textbf{False}}

Explanation:

<u>Definition of weight:</u>

  • The gravitational force acting on a body is called weight.

<u>Explanation:</u>

The weight of the body changes with different factors concerned e.g. height h, acceleration due to gravity g etc.

We know that,

W = mg

Mass is a constant quantity, however g changes with the altitude or place. Consequently, weight also does not remain constant.

<u>Example:</u>

An object having mass 1 kg will have a weight of 9.8 N on Earth while its weight on moon will be 1.6 N due to the difference in the values of g.

Leya [2.2K]

The question is incomplete, here is the complete question:

The rate constant of a certain reaction is known to obey the Arrhenius equation, and to have an activation energy Ea = 71.0 kJ/mol . If the rate constant of this reaction is 6.7 M^(-1)*s^(-1) at 244.0 degrees Celsius, what will the rate constant be at 324.0 degrees Celsius?

<u>Answer:</u> The rate constant at 324°C is 61.29M^{-1}s^{-1}

<u>Explanation:</u>

To calculate rate constant at two different temperatures of the reaction, we use Arrhenius equation, which is:

\ln(\frac{K_{324^oC}}{K_{244^oC}})=\frac{E_a}{R}[\frac{1}{T_1}-\frac{1}{T_2}]

where,

K_{244^oC} = equilibrium constant at 244°C = 6.7M^{-1}s^{-1}

K_{324^oC} = equilibrium constant at 324°C = ?

E_a = Activation energy = 71.0 kJ/mol = 71000 J/mol   (Conversion factor:  1 kJ = 1000 J)

R = Gas constant = 8.314 J/mol K

T_1 = initial temperature = 244^oC=[273+244]K=517K

T_2 = final temperature = 324^oC=[273+324]K=597K

Putting values in above equation, we get:

\ln(\frac{K_{324^oC}}{6.7})=\frac{71000J}{8.314J/mol.K}[\frac{1}{517}-\frac{1}{597}]\\\\K_{324^oC}=61.29M^{-1}s^{-1}

Hence, the rate constant at 324°C is 61.29M^{-1}s^{-1}
