WebOkay, guys, in this problem, we are given the fact that the probability 32 different probabilities were told that the probability that it will rain on Saturdays 40%. bbu 22WebThe rate's unit is given as molarity per second, or M/s, and the concentration uses just units of molarity, M. So writing the same rate law with just the units: M/s = k*M, we see that for both sides of the equation to have the same unit the rate constant must be 1/s or s^(-1). This is because M*1/s = M/s, the same unit as the rate's unit. dca to sju nonstop
