how to use a table to figure out the rate constant

Initial rate data at a certain temperature is given in the table for the reaction N2O3(g) → NO(g) + NO2(g) [N2O3] (M) 0.100 0.200 0.300 Rate (M/s) 0.750 1.500 2.250 Determine the value of the rate constant, assuming units of 1/s Type your answer...

The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product.    Using the internet , research the pressure  factor below that affect the rate of a chemical reaction.    1. pressure  ( be very detailed add graphs to explain your details it should be 300 words )  Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!
