Instantaneous rate expression can written as
For the first order reaction for the gases phase given by
we have give p1 = 84mm
total pressure =110mm
at the time = 16 min
thus applying in above formula
For a given reaction
A + B → 2C
we have given
the rate of disappearance of A is 10-2 moles L–1 sec–1
(ii)
rate of expression can be written as
since rate of disappearance of A is given to be 10-2 moles L–1 sec–1
thus
rate of disappearance B 10-2 moles L–1 sec–1
(iii)
for Ans. (i) 10–2 mol L–1 sec–1 (ii) 2 x 10–2mole L–1 sec–1
A reaction in which the rate is independent of the concentration of the reactants.
