Consider the reaction, 2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g) When H is increasing at 0.85 mol/Ls, how quickly is F decreasing?
The reaction is as follows:
2D(g) + 3E(g) + F(g)
2G(g) + H(g)
The rate expression for the reaction is as follows:
Rate = -1/2{[D]/
t}
= -1/3{
[E]/
t}
= -
[F]/
t
= 1/2{
[G]/
t}
=
[H]/
t
The rate of change of H {[H]/
t}=
0.85 mol/L
The relation between
[F]/
t
and
[H]/
t
is as follows:
As per the rate expression,
Negative sign indicates that F is decreasing.
Hence, F is decreasing with a rate of 0.85 mol/L.s.
