Question

Predict how decreasing the volume of the container used for the reaxtion below affect the initial rate of the reaction and explain your prediction.
H2(gas) + I2(gas) ---> HI2

Answer 1

Decreasing the volume increases the pressure, therefore due to Le Chatelier's principle, we can see that more HI2 will be formed as 2 molecules combine into 1 and that conserves space which in turn lowers the pressure.
