According to table i, which equation represents a change resulting in the greatest quantity of energy released? 2c(s) + 3h2(g) → c2h6(g) 2c(s) + 2h2(g) → c2h4(g) n2(g) + 3h2(g) → 2nh4(g) n2(g) + o2(g) → 2no(g)

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
