Question

pts) The synthesis of ammonia from nitrogen and hydrogen is exothermic N2(g) + 3H2(g) → 2NH3(g) + Heat )If heat is removed, will the forward rate of the reaction increase or decrease? Why? ) If nitrogen gas is added, will the forward rate of the reaction increase or decrease? Why? If the volume of the reaction container is increased, how will this affect the rate of the forward reaction? Why? )

Answer 1

a) In this reaction, N2 and H2 are the reactants and NH3 is product.

This is exothermic reaction.

When heat is removed then forward reaction occurs. So rate of forward reaction increases.

b) As the N2 is reactant. We know with increasing the concentration of reactant, rate of the forward reaction increases.

so here rate of forward reaction increases.

c) In the forward reaction volume is decreased because 4 mole gas produce 2 mole gas(NH3).

so volume of container increases, the rate of forward reaction decreases.
