Inhibitor

Explanation:

Adding an inhibitor will slow down a chemical reaction. Inhibitors works like a negative catalyst.

The addition of a foreign body can influence the rate of a reaction.

  • When a foreign body slows down a reaction, it is called an inhibitor.
  • An inhibitor is a negative catalyst that will slow down a reaction.
  • Such substances do not allow a reaction to proceed freely and very fast.
  • They work in the opposite way a normal catalyst would.
  • It is good to know conditions and chemicals that can inhibit a chemical reaction.

Determine the volume, in liters, occupied by 0.015 molecules of oxygen at STp?
Arlecino [84]

5.58 X 10^{-25} Litres is the volume, in liters, occupied by 0.015 molecules of oxygen at STP.

Explanation:

Data given:

molecules of oxygen = 0.015

number of moles of oxygen =?

temperature at STP = 273  K

Pressure at STP = 1 atm

volume = ?

R (gas constant) = 0.08201 L atm/mole K

to convert molecules to moles,

number of moles = \frac{molecules}{Avagadro's number}

number of moles = 2.49 x 10^{-26}

Applying the ideal gas law since the oxygen is at STP,

PV = nRT

rearranging the equation:

V = \frac{nRT}{P}

putting the values in the rearranged equation:

V = \frac{2.49 X10^{-26}   X 0.08201 X 273}{1}

V = 5.58 X 10^{-25} Litres.
