What are the units of the rate constant, ?

2

Why does a higher temperature result in a faster reaction?

3

Two moles of nitrogen gas are kept in a glass container. The temperature of the gas is 400K.

What is the kinetic energy of the gas?

$R=8.314\frac{J}{mol*K}$

6

Consider the following first order reaction

$A\overset{k}{\rightarrow}B$

Where k is the rate constant.

$k=0.001s^{-1}$

and the initial concentrations of A and B are
