Kinetic Theory ...

If $$\triangle E$$ is the heat of reaction for $${ C }_{ 2 }{ H }_{ 3 }{ OH }_{ \left( 1 \right)  }+{ 3O }_{ 2\left( g \right)  }\rightarrow { 2CO }_{ 2\left( s \right)  }+3{ H }_{ 2 }{ 0 }_{ \left( 1 \right)  }$$ at constant volume, the $$\triangle H$$ ( Heat of reaction at constant pressure) at constant temperature is:

Ideal monoatomic gas is taken through a process $$dQ  =2dU$$. What is the molar heat capacity for the process? ( where dQ is heat  supplied and dU is change in internal energy)

A vessel has $$6g$$ of oxegen at pressure $$P$$ and temperature $$400\ K$$. A small hole is made in it so that oxygen leaks out. How much oxygen leaks out if the final pressure is $$P/2$$ and temperature is $$300\ K$$

Three particles are situated on a light and rigid rod along Y-axis as shown in the figure. If the system is rotating with angular velocity of $$2 rad/sec$$ about X axis, then the total kinetic energy of the system is :

We have a jar A filled with gas characterized by parameters P, V and T and another jar B filed with gas with parameters 2P, Vl4 and 2T, where the symbols have their usual meanings. The ratio of the number of molecules of jar A to those of jar B is 

The degrees of freedom of a triatomic gas is? (consider moderate temperature)

Change in momentum of the gas molecules as they strike the walls
One mole of an ideal gas (mono-atomic) at temperature $$T_{0}$$ expands slowly according to law $$P^{2} = cT$$ ($$c$$ is constant). If final temperature is $$2T_{0}$$, heat supplied to gas is

At what temperature does the average translational kinetic energy of a molecule in a gas become equal to kinetic energy of an electron accelerated from rest through a potential difference of $$1 \ volt$$?$$(k=1.38\times10^{23} \ J/k)$$

The effect of temperature on Maxwell's speed distribution is correctly shown by 

Calculate $$\gamma $$ (ratio of $$C_p$$ and $$C_v$$ ) for triatomic linear gas at high temperature. Assume that the contribution of the vibrational degree of freedom is 75%?
