For the traditional van't hoff equation where obviously R is constant, and assuming we know and at a given temperature T we can calculate K. If you are referring to the version of the van't hoff equation where you can convert between two K values at different temperatures, i.e. then we are assuming that is constant at both temperatures so that it does not change and we can use it in our calculation (again R is also constant). To solve this equation you would need to be given at least 3 of the 4 variables, and it is most often used when given K1 at T1 and you are asked to find K2 at a given T2.
