pls help ill thumbs up

A student obtained the following data for the decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30 C. N2052 NO2(g) + V2 O2(9) [N205), M time, min 0.292 0 0.146 131 7.30X10-2 262 3.65x10-2 393 (1) What is the half-life for the reaction starting at t = 0 min? min What is the half-life for the reaction starting at t = 131 min? min Does the half-life increase, decrease or remain constant as the reaction proceeds? (2) Is the reaction zero, first, or second order? (3) Based on these data, what is the rate constant for the reaction? min A student obtained the following data for the decomposition of hydrogen lodide on a gold surface at 150 C.
