The balanced equation for the reaction of bromate ion with bromide in acidic solution is at a particular instant in time, the rate of disappearance of br– is 2.0 x 10⁻³ mol/l • s. what is the rate of appearance of br₂ at the same instant?

The rate of appearance of Br₂ at the same instant is 0.0012 mol/L.

Explanation:

The rate of disappearance of :

Rate of the reaction in terms of bromide ions : R

Rate of the reaction in terms of bromine gas : R

=3\times 0.0004 mol/L=0.0012 mol/L[/tex]

The rate of appearance of Br₂ at the same instant is 0.0012 mol/L.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
