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,
-[F]/t = [H]/t
[F]/t = -[H]/t
[F]/t = - 0.85 mol/L.s
Negative sign indicates that F is decreasing.
Hence, F is decreasing with a rate of 0.85 mol/L.s.
