In a reversible reaction, increase in pressure favours that reaction where the number of moles
Decreases
Increases
Remains same
First increases then decreases

H2 +I2 ↔ 2HI When pressure is increased, the equilibrium
Unaffected
Zero
When rate of forward reaction is equal to the rate of backward reaction, the system is said to be in a state of
Zero reaction
Equilibrium
Constant motion
None of these
