The first reaction will be more favorable to the right, since the carbocation is formed in the first reaction is more stable because of three CH3 group providing inductive effect and hyperconjugation (+I,+H effect) whereas in the second reaction, the CF3 will be acting as -I group, hence will snatch the electrons from carbocation making it more unstable
Hence the first reaction will have an equilbrium constant more favorable to the right

It is possible to predict the equilibrium constant of a reaction by combining two or more reactions for which the value of K is known. When combining equilibrium constants, it is important to note the following: When a reaction is reversed, its Kvalue is inverted; that is, Kreverse=1/Kforward. When the coefficients of a reaction are multiplied by a factor, the K value is raised to the power of that factor. When reactions are added, their Kvalues are multiplied. Part A...
