QUESTION 1 Which of the following statements is true for the following reaction? A. The reaction is spontaneous only at relatively high temperatures B. The reaction is at equilibrium under standard-state conditions. e C. The reaction is not spontaneous at any temperature D. The reaction is spontaneous at all temperatures O E. The reaction is spontaneous only at relatively low temperatures. QUESTION 2 Which of the following is not 3 spontaneous process at 25 C and 1 atm pressure? A salt dissoving B. steam,condensing C water boiling D.iron nusting E ice meltin
