Q1
In a reversible reaction at equilibrium, what happens if the temperature is increased? (2019)
The reaction shifts to the exothermic side
The reaction shifts to the endothermic side
No change occurs
The reaction rate decreases
Increasing the temperature of an exothermic reaction shifts the equilibrium to the left (towards the reactants), while for an endothermic reaction, it shifts to the right (towards the products).

Q: In a reversible reaction at equilibrium, what happens if the temperature is increased? (2019)
Solution: Increasing the temperature of an exothermic reaction shifts the equilibrium to the left (towards the reactants), while for an endothermic reaction, it shifts to the right (towards the products).
Steps: 5
Step 1: Understand that a reversible reaction can go in two directions: from reactants to products and from products to reactants.
Step 2: Know that reactions can be classified as exothermic (release heat) or endothermic (absorb heat).
Step 3: If the temperature of an exothermic reaction is increased, the system will try to counteract this change by favoring the direction that absorbs heat, which is towards the reactants (left).
Step 4: If the temperature of an endothermic reaction is increased, the system will favor the direction that produces heat, which is towards the products (right).
Step 5: Remember that increasing temperature affects the position of equilibrium based on whether the reaction is exothermic or endothermic.
