Question

Consider the following equilibrium:

CO_(g) + 2H_2(g)⇌ CH₃OH_(g)+ energy

Which of the factors below would decrease the concentration of CH₃OH at equilibrium?

	a.	a decrease in the temperature
	b.	an increase in the temperature
	c.	an addition of CO
	d.	an increase in H₂

Answer 1

Answer #1

The reaction produce heat, so it is exothermic reaction

For exothermic reaction, de-creasing temperature shift the equilibrium to right side and increasing conc of CH3OH.

For exothermic reaction, increasing temperature shift the equilibrium to left side and decreasing conc of CH3OH.

CO is a reactant. Addition of reactants, shifts the equilibrium to right side and increase the conc of CH3OH

Similarly, H2 is also a reactant. Addition of reactants, shifts the equilibrium to right side and increase the conc of CH3OH

Answer:

b.	an increase in the temperature
