You need to compare the E reduction value of both Cr^2+ and I2 and see which one will be oxidised and reduced more readily. Then you will have to calculate the Ecell value of the overall reaction to see and see if the value is positive or negative. If it is positive, it means that the reaction occurs spontaneously.
