Question

1. Chemical equilibrium is established when the number of reactants equals the number of products.

- True
- False

2. According to Le Chatelier's principle, by increasing the temperature of the system shown below, the equilibrium will shift to the right (towards products).

A + B heat + AB

- True
- False

3. For which of the following reactions will an increase in pressure not effect the position of equilibrium?


A. 2A2 (g) + B2 (g) 2A2B (g)

B. 2AB (g) A2 (g) + B2 (g)

C. 2A (g) + F2 (g) 2AF (g)

D. 2B (s) + 2HA (aq) 2BA (aq) + H2 (g)

Answer 1

1)false a in chemical equilibrium concentration of reactant is equal to concentration of product

2)as here they said heat is added in product side means its endothermic reaction and in endothermic reaction on increasing temp. equilibrium shift towards forward direction so its true

3) B)as here mole are equal in reactant and product side that is 2 and if we increase pressure equilibrium shift in dat direction where no. of moles are less and here mole are equal so it will remain unaffected
