Answer:
0.023 mol/(L*s).
Explanation:
Equation of the reaction:
2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g)
Using stoichiometry, 2 moles of D reacts with 3 moles of E and 1 mole of F to give the above products.
1 mole of D will react with 3/2 moles of E.
Delta[D]/delta t = 0.15 mol/L.s
Delta[E]/delta t = (3/2) * 0.15 =
= 0.023 mol/(L*s).
