Total distance divided by total elapsed time gives what quantity?
ki77a [65]
<h2>Total distance divided by total elapsed time gives : Average speed </h2>

Explanation:

Speed

It is the distance traveled by body with respect to time .

Its formula is Speed = distance /time

V=S/T

units : m/sec or Km/hr

Distance

It is total path traveled by body in any direction .

It unit and symbol is : S  and unit = m /Km

Average speed

It is the total distance traveled by body with respect to total time taken to travel that given distance .

Average speed = total distance /total time

A.s = T.D/T.T

unit = m/sec or Km/hr

Instantaneous velocity

It is the distance traveled by body at particular instant of time ,in given direction .

Displacement

It is the shortest path traveled by body in given direction .

For each of the following cases, identify the order with respect to the reactant, A. Case (A ----&gt; product)
damaskus [11]

Answer:

The answers to the question are

1. 2nd and above order order

2. 2nd order

3. 1/2 order

4.  1st order

5. 0 order

Explanation:

We have \frac{N}{N_{0} } = e^{-\lambda t}

1. For nth order reaction half life  t_{\frac{1}{2} } ∝ \frac{1}{[A_{0} ]^{n-1} }

Therefore for a 0 order reaction increasing concentration of the reactant there will increase   t_{\frac{1}{2} }

First order reaction    is independent  [A₀].

Second order reaction  [A₀] decrease,    increase.

Similarly for a  third order reaction

1. 2nd order

2. 2nd order reaction

3. Order of reaction is 1/2.

4. 1st order reaction.

5. Zero order reaction.
