Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. what volume of hydrogen chloride
Anna71 [15]
The reaction between methane gas and chlorine gas to form hydrogen chloride and carbon tetrachloride, all in their gaseous form can be expressed through the chemical reaction below.

        CH₄ + 4Cl₂ --> 4HCl + CCl₄

Let us assume that all the involved gases behaves ideally such that each mole of the gas is equal to 22.4 L. 

Through proper dimensional analysis, the volume of the produced hydrogen chloride is calculated,
    V(HCl) = (1.69 mL CH₄)(1 L CH₄/ 1000 mL CH₄)(1 mol CH₄/22.4 L CH₄)(4 mols HCl/1 mol CH₄)(22.4 L HCl/1 mol HCl)(1000 mL/1 L)
    

    V(HCl) = 6.76 mL

<em>ANSWER: 6.76 mL</em>

Can someone easily explain to me how to do reaction rates?
iVinArrow [24]

Explanation:

Reaction rate is a measure of speed of a chemical reaction.

Usually, based on rates, reactions can be divided into two parts:

  • Slow reactions which usually takes a long time.
  • Fast reactions which takes place completely in seconds or microseconds.

Reaction rate can be defined as a change in the concentration of a reactant or product per unit time:

      The unit is  mol dm⁻³ s⁻¹

Reaction rate = \frac{change in concentration of a reactant and product}{time taken }

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
