 Okay, let's take a look at another dimensional consistency problem here concentration is given by C equal to let's say 0.03 exponential K or 2 times T. Let's say if we have this expression what should be the dimensions here K is basically measured as let's say I'm giving you this units as kilograms per liter so this is how we are measuring C so this 0.03 what should be the dimensions here and what should be the dimensions of this one this because exponent should be dimensionless here this 0.03 should have dimensions of kilograms per liter okay and exponent should be two times this dimensionless two times T should be dimensionless and this is measured in seconds so this should be one over second that way these two can get cancelled and this will be dimensionless so that's one way of looking at it
