Calculate the ΔHrxn for the following reaction: CH4 (g) + 2Cl2 (g) - - > CH2Cl2 (g) + 2HCl (g) Use the following reaction and given ΔH's: CH4 (g) + Cl2 (g) - - > CH3Cl (g) + HCl (g), ΔH = - 99.

Select all that apply to diffusion. A solid cannot diffuse in to another solid. Solids can diffuse in liquids. Liquids can diffuse in liquids. It is the process of intermingling atoms from one substance into another.

We are all familiar with the general principles of operation of an internal combustion engine: the combustion of fuel drives out the piston.

A first order reaction has a rate constant of 0.816 at 25 oC. Given that the activation energy is 22.7 kJ/mol, calculate the rate constant at 34 oC. (enter answer to 3 decimal places)
