The critical temperature of `O_(2)` and `N_(2)` are `155K` and ` 126 K` respectively Calculate the ratio of reduced temperature of `O_(2)` and `N_(2)` at `300 K` .

Explanation

For `O_(2) : T_(r1) = (T)/(T_(c_(1)) )= (300)/(155)`
For `N_(2): T_(r_(2)) = (T)/(T_(c_(2))) = (300)/(126)`
`:. (T_(r_(1)))/(T_(r_(2))) = (126)/(155) = 0.812`
