Although C_(P) is usually assumed to be constant, for more accurate calculations we must consider its variation with temperature as well. This relation is given by : C_(P) = a + b T + c T^(2) + d T^(3) mol^(-1) K^(-1) For CO_(2), a = 5.0 , b = 15 xx 10^(-5) .Find the heat required (for one mole) to raise its temperature from 300 K to 500 K in case (i) and case (ii). Case (ii) gives a more accurate value. Find the percent error in case (i)
