For the reaction: $A + B + Q \rightleftharpoons C + D$,if the temperature is increased,then the concentration of the products will

The reaction $CaCO_3 \rightleftharpoons CaO + CO_{2(g)}$ goes to completion in a lime kiln because:

In the $N_2 + 3H_2 \rightleftharpoons 2NH_3$ reversible reaction,an increase in pressure will favour:

$A$ vapor at atmospheric pressure is gradually heated from $25\,^oC$. Initially,its color deepens,but above $160\,^oC$,the color fades. At $600\,^oC$,the vapor becomes almost colorless. However,increasing the pressure at this temperature makes the color deep again. What is this vapor?

Which among the following reactions is favoured in the forward direction by an increase in temperature?

What happens when an inert gas is added at constant pressure to a reversible decomposition reaction that is in equilibrium?
