The equilibrium constant k for a certain reaction was measured as a function of temperature (in kelvin). a plot of ln(k) versus 1/t for this reaction gives a straight line with a slope of 1.352 x 104 k and a y-intercept of -14.51. determine the value of δh° for this reaction.

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

A. to determine if humans can explore mars safely

Sorry i don’t know what to do

Initial velocity,  u = 4.9 m/sfinal velocity = v m/sinitial height,  h₁ =  245 m    final height, h₂ = 0a = -9.8  m/s²time taken = t secondss = ut + 0.5at²⇒  (h₂-h₁) = ut + 0.5at²⇒  0-245 = 4.9t + 0.5×(-9.8)×t²⇒ -245 = 4.9t - 4.9t²⇒ 4.9t² -4.9t -245 =0solving it, we get   t = 7.59sv  = u +  at = 4.9 -9.8×7.59 = 4.9 - 74.38 = -69.48 m/svelocity is  69.48 m/s downward
