Which option is valid for zero order reaction?

Flask with greater mean free path for the molecules.($$r_{H_2}:r_{CH_4}:r_{O_2}=1:2:2$$)

The number of collisions of Ar atoms with the walls of container per unit time?

Flask with greater number of collisions with the walls per unit area per unit time.

If X is the total number of collisions which a gas molecule registers with other molecules per unit time under particular conditions, then the collision frequency of the gas containing N molecules per unit volume is:

When the temperature of an ideal gas is increased at constant pressure?

In a closed flask of $$5$$ litres $$1.0\ g$$ of $$H_2$$ is heated from $$300$$ to $$600\ K$$. Which statement is not correct?

One mole of helium and one mole of neon are taken in a vessel. Which of the following statements are correct?

A container (cylindrical, base area$$=821cm^2$$) fitted with frictionless, massless piston consists of five valves-I, II, III, IV, and V. The distance of valves from the initial position of the piston is $$15, 30, 40, 45$$ and $$50$$cm, respectively. The initial height of the piston from the base of the container was $$60$$cm. These valves open automatically if pressure exceeds over $$1.5, 2.2, 2.5, 4.4$$, and $$4.8$$ atm, respectively. Under the given conditions(shown in the diagram), the system is in a state of equilibrium. The piston is now compressed(moved downward) slowly and isothermally. Neglect the volumes of valve connectors. Select the correct option(s).

The order of a reaction is zero. It will be definitely
