Answer:
Decreasing the concentration of N2O3
Explanation:
This is because the products on the right of the reaction occupy more space. One (1) mole of NO and another mole of NO2 will occupy more space than the one (1) mole of N2O3. Therefore decreasing the concentration of N2O3 will shift the reaction to the right because the products will have more space to occupy – hence favoring equilibrium.
Answer:
i.e belongs to same group because of valence electrons are same
Explanation:
so it has same chemical behaviour. and q has more energy than r ionisation energy decreases from top to bottom
