Q

what is le chateliers principle

A

if a dynamic equilibrium is disturbed by a change in conditions, the position of the equilibrium will shift to counteract that change

Q

if a reaction produces an increase in pressure, what happens to larger volume of gas ( more moles in products)

Q

if a reaction produces an increase in pressure, what happens to smaller volume of gas ( less in products)
