(3 points) a second order chemical reaction involves the interaction (collision) of one molecule of a substance with one molecule of another substance to produce on molecule of a new substance this is denoted by +→ the rate of this reaction is modeled by the differential equation =−− where is the amount of substance at time and > 0 are the initial amounts of substances and respectively. suppose that 18 moles of substance and 12 moles of substance react together. if =0.022 1/(mol⋅sec) and )=0, find the amount of time until there are 10 moles of substance
