q and change in T

Postby Ekayana Sethi 2K » Tue Feb 13, 2018 8:06 pm

When reaction is endothermic at q is positive is change in T always positive implying that Tfinal is greater than T initila and the temperature was increased?

Yup you can assume that, unless there's a specific condition stating that temperature is constant, such as when a system is isothermal (meaning that the heat that is inputted is cancelled out by the system doing work so that there is no temperature change).
