Answer to Question #166271 in General Chemistry for Isabella Iovene

Question

1. Consider the following reaction: (14 pts .) 2SO 3 (g)+CO 2 (g)+heat CS 2 (g)+ 4O 2 (g) Indicate in which direction the equilibrium will shift due to : a.) an increase in pressure b.) the addition of SO 3 .) a decrease in the concentration of CS 2 d.) an increase in temperature e.) the addition of O 2 f.) List three conditions that would increase the rate of the reaction, and explain why each would increase the rate based upon the collision theory.

Answer 1

a) equilibrium will shift to the reagents

b) equilibrium will shift to the products

c) equilibrium will shift to the products

d) equilibrium will shift to the products

e) equilibrium will shift to the reagents

f) If you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction will be.

There are three important parts to collision theory, that reacting substances must collide, that they must collide with enough energy and that they must collide with the correct orientation .
