According to Boyle's law:

Pressure of given mass of ideal gas is inversely proportional to its volume at a constant temperature.

That can be represented as:

PV=Constant

Where P represents pressure, V represents volume.

Here as the volume increases that is from 20 L to 27 L, So pressure must decreases, so the original pressure must be greater than 120 kPa.

So the answer is "The original pressure must be more than 120kPa because when P increases, V decreases".

Distinguish between accuracy and precision in measurements

nignag [31]

The accuracy is associated with magnitude of fractional error or relative error in that measurement

the precision of a measurement is associated with least count of the measuring instrument.

precision does not mean accuracy but both are highly demanded while making measurements in physics.

The decomposition of acetaldehyde is a second order reaction with a rate constant of 4.71 10−8 L/mol/s. What is the instantaneou

Answer: Rate of decomposition of acetaldehyde in a solution is $1.45\times 10^{-14}mol/Ls$

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

For a reaction : $A\rightarrow products$

$Rate=k[A]^x$

k= rate constant

x = order of the reaction = 2

$Rate=4.71\times 10^{-8}L/mol/s\times {5.55\times 10^{-4}M}^2$

$Rate=1.45\times 10^{-14}$

Thus rate of decomposition of acetaldehyde in a solution is $1.45\times 10^{-14}mol/Ls$
