Consider the reaction: CO + 2 H2 <----> CH3OH?

Question

All substances are in the gaseous state and, ΔH = –92 kJ.
Predict whether the reactants (left side) or the products (right side) will be favored by the following changes.
i. increased pressure.
ii. increased temperature.
iii. addition of hydrogen .
iv. removal of the product, CH3OH .

Answer 1

i. Increasing the pressure by reducing the volume will favor the side with the less number of molecules, the products.

ii. reaction is exothermic, so temperature increase will favor the reactants.

iii. adding a reactant favors products formation.

iv. removing a product favors products formation.

Answer 2

1. products
2. reactants
3. products
4. products

Answer 3

i. product
ii. reactant
iii. product
iv. product...le chatelier principle
