For this problem, we are being asked to calculate the lowest temperature at which the reaction is spontaneous in the forward direction

• In order for a reaction to be spontaneous or favor the forward reaction, Kp must be greater than 1 or ln(Kp) must be greater than 0
• In this case, we have to find the 1/T when ln(Kp) = 0
• Notice that this will be the y-intercept of the graph which can be seen as 1.4
