the time signature 2/4 indicates how many beats in a measure
Time signature For instance, 2 4 means two quarter-note (crotchet) beats per bar, while 3 8 means three eighth-note (quaver) beats per bar. The most common simple time signatures are 2 4, 3 4, and 4 4.
Beat (music) In typical Western music 4 4 time, counted as "1 2 3 4, 1 2 3 4...", the first beat of the bar (downbeat) is usually the strongest accent in the melody and the likeliest place for a chord change, the third is the next strongest: these are "on" beats. The second and fourth are weaker—the "off-beats". Subdivisions (like eighth notes) that fall between the pulse beats are even weaker and these, if used frequently in a rhythm, can also make it "off-beat".[8]

Rate equation k is the first order rate constant, which has units of 1/s or sâˆ’1.
