Idk but you can try to look it up. On google or somewhere else but yea idk about that one
100.3kcal of heat will be absorbed.
2moles of NO absorb 43kcal.
I mole of NO weighs 14 +16 = 30g so 2 moles weigh 60g.
So 60g absorb 43kcal
So 1g absorb 43/60 kcal
So 136g absorb (43/60) x 136 = 97.47 kcal
Answer: All solids absorb heat as they melt to become liquids.
Explanation:
According to the decomposition of XY is second order, and we assume that the rate constant (K) = 6.92 X 10^-3 M^-1 :
So according to this formula:
Kt= 1/[XY]t - 1/[XY]o
when [XY]o is the initial concentration = 0.1 m & [XY]t is the concentration after passing a period of time= 0.1 x 0.125 = 0.0125 m
and when K= 6.92X10^-3 M^-1
By substitution:
t = (1/[XY]t - 1/[XY]o) / K
=(1/0.0125 - 1/0.1) / 6.92X10^-3
∴t = 1011 S = 17 min
