And it's not hard to see how the heat of reaction at room temperature can be related to they heat of reaction at other temperatures.

知道室温下的反应热,如何与其他温度下的反应,热联系起来这点并不困难。

We can tabulate them. We can know them, and then when we have reactions that inter-convert different compounds, we can calculate the heat of reaction is just the difference between the heat of formation of the reactants, and the heat of formation of the products, right.

种化合物的生成热，可以把它们列成表,可以认知它们，而当我们要处理，在不同化合物间转变的反应时,我们只要计算反应物和,生成物的生成热之间的不同,就能计算出反应热。
