+25 kJ; not spontaneous is your answer :) Hope this helps.
the Percentage yield for the reaction = 48.8%
What is Percentage yield ?
The % ratio of the theoretical yield to the actual yield is known as the percent yield. It is calculated as the theoretical yield multiplied by 100% divided by the experimental yield. The percent yield is 100% if the theoretical and actual yields are equal. Because the real yield is frequently lower than the theoretical value, percent yield is typically lower than 100%. This may be due to incomplete or conflicting reactions or sample loss during recovery. If the percent yield is more than 100%, more sample than expected was retrieved from the reaction.
4 P + 3 O2 = P4O6
moles P = 75.3 g / 30.9738 g/mol= 2.43
moles O2 required = 2.43 x 3 / 4=1.82
actual moles O2 = 38.7 g /32 g/mol=1.21 so O2 is the limiting reactant
theoretical moles P4O6 = 1.21 / 3=0.403
theoretical mass P4O6 = 0.403 mol x 219.895 g/mol=88.6 g
% yield = 43.3 x 100/ 88.6 = 48.8 %
the Percentage yield for the reaction = 48.8%

Temperature can be calculated using the average kinetic energy. The ideal gas equation is being related to the average molecular kinetic energy.

PV = nRT
</span><span>PV = (2/3) N(0.5mv^2)
</span><span>
By substituting and simplifying, we eventually get the equation.

KE = (3/2)RT</span>
T = 3866 x 2 / 8.3145 x 3 = 309.98 K or 36.83 degrees Celsius
