The following reaction : 2A(g)+B(g)→C(g)+D(l), Change H>0 will be spontaneous at:
A) low temperature B)High Temp C) All Temp D) No temp
2A(g)+B(g)→C(g)+D(l)
H = -ve
It is exothermic reaction . The exothermic reaction takes place at low temperature.
At low temperature the reaction is spontaneous
Change H>0 will be spontaneous at low temperature
A) low temperature >>>>answer
