1.	When NaNO_(3) is heated in a closed vessel, O_(2) is liberated and NaNO_(2) is left behind. At equilibrium: NaNO_(3(g)) hArr NaNO_(2(g)) + (1)/(2) O_(2(g))
Answer» addition of `NaNO_2` favours reverse reaction addition of `NaNO_2` favours FORWARD reaction increasing temperature favours forward reaction increasing pressure reduces the RATE of forw ARD reaction Solution :Le-chatelier.s principle
