Answer to Question #196848 in Inorganic Chemistry for Alex

Question

Looking at equation B, what will happen to the reaction rate if pressure is decreased in the reaction vessel?

EQUATION B:

2 SO2(g) + O2(g) --> 2 SO3(g)

a. decreases

b. stays the same

c. increases

Answer 1

there is a decrease in pressure than the equilibrium will shift towards the side of the reaction with more moles of gas.

That is backward , this means that the

Rate of reaction decrease.

Option (a. )decreases
