Based on Gay-Lussac's law, which of the following statements is true for an ideal gas at constant volume and mole amount?

a - the number of collisions is independent of pressure
b - the number of collisions decreases with increase in pressure
c - pressure is directly proportional to the absolute temperature
d - pressure is inversely proportional to the absolute temperature

C. pressure is directly proportional to the absolute temperature

Explanation:

Gay- Lussac's law is defining a relationship between the pressure and temperature at a constant volume for an ideal gas.The law says that when there is an increase in the temperature of the ideal gas then the pressure of the gas is also increasing. There created a direct relationship between temperature and pressure. Option A tells us that collision and pressure are not related which is not true, Option B is saying that as pressure increases the collisions of the gas particles decreases which is not correct, Option C is drawing the correct relationship between pressure and temperature, and option D is talking the reverse of option C which is incorrect. Hence, the answer is C
