For a reaction : M + 2N → P + 2Q, the initial rate , − []/ is 2.4 x 10-2 Ms-1 . What is the value of − []/ ?

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
